Textile & Clothing Repair
The average American throws away 81 pounds of clothing per year. Most of it has fixable problems — a missing button, a split seam, a small hole. A $15 sewing kit and 10 minutes of skill can save you $200-500 a year and keep clothes you actually like wearing. This skill covers the 8 repairs that handle 90% of clothing damage, plus when to give up and take it to a tailor.

# Localization note
- Fabric care symbols are standardized internationally (ISO 3758) but terminology
varies: "jumper" (UK/AU) = "sweater" (US), "trousers" (UK) = "pants" (US)
- Swap measurement units: inches (US) to centimeters (metric countries)
- Tailor pricing varies significantly by region — adjust cost estimates
- Dry cleaning terminology and availability differs; some regions use
different solvent standards
- Detect user country and swap local fabric store chains

CODEBLOCK1
SEW A BUTTON:
THREAD THE NEEDLE:
1. Cut 24 inches of thread
2. Thread one end through the needle eye
(wet the end and pinch it flat if it won't go through)
3. Pull through until you have two equal lengths
4. Tie the two ends together with a double knot
(you're sewing with doubled thread for strength)
POSITION THE BUTTON:
1. Find where the button was (look for thread remnants or the mark)
2. Hold button in place on the RIGHT side of the fabric
SEW:
1. Push needle up from the BACK of the fabric, through one button hole
2. Push needle down through the opposite hole, through the fabric
3. Repeat 4-6 times through each pair of holes
4. For 4-hole buttons: sew in an X pattern or parallel lines
(match the pattern on the garment's other buttons)
CREATE A SHANK (for non-flat buttons like on coats):
1. After the last stitch, bring the needle up between the button
and the fabric (not through a hole)
2. Wrap the thread around the threads under the button 5-6 times
3. This creates a "stem" that gives room for the buttonhole fabric layer
TIE OFF:
1. Push needle to the back of the fabric
2. Make a small stitch, loop the thread through it twice
3. Pull tight, cut the thread
4. Done. Total time: 5-10 minutes.
CODEBLOCK2
FIX A SPLIT SEAM:
IDENTIFY THE PROBLEM:
- A split seam means the THREAD broke, not the fabric
- The fabric edges are still intact with the original stitch holes visible
- This is the easiest repair — you're just reconnecting two edges
USE A BACKSTITCH (strongest hand stitch):
1. Thread needle with matching thread, doubled, knotted at the end
2. Turn the garment inside out
3. Start 1/2 inch before the split (overlap with existing stitching)
4. Push needle up through the fabric from the back side
BACKSTITCH TECHNIQUE:
1. Insert needle 1/8 inch BEHIND where the thread comes out
2. Bring it up 1/8 inch AHEAD of where the thread comes out
3. Insert needle back at the point where the previous stitch ended
4. Bring it up 1/8 inch ahead again
5. Repeat — each stitch goes backward, then forward
6. Continue 1/2 inch past the end of the split
7. Knot off on the inside
WHY BACKSTITCH:
- It creates a continuous line of stitching with no gaps
- Stronger than a running stitch
- Looks nearly identical to machine stitching from the outside
CODEBLOCK3
PATCHING METHODS BY HOLE SIZE:
SMALL HOLE (under 1/4 inch) — DARN IT:
1. Thread needle with matching thread
2. Make tiny parallel stitches across the hole
3. Then weave perpendicular stitches through them
4. You're creating a tiny fabric grid to fill the gap
5. Best for: knits, sweaters, socks
MEDIUM HOLE (1/4 inch to 1 inch) — IRON-ON PATCH:
1. Cut an iron-on patch 1/2 inch larger than the hole on all sides
2. Turn garment inside out
3. Place patch adhesive-side down over the hole
4. Iron on medium heat for 30-45 seconds with firm pressure
5. Let cool completely before moving
6. Best for: jeans, cotton, canvas
LARGE HOLE (over 1 inch) — SEW-ON PATCH:
1. Cut a patch from matching or complementary fabric
(old jeans, bandana, etc.)
2. Cut patch 1 inch larger than the hole on all sides
3. Pin patch in place over the hole
4. Fold raw edges of patch under 1/4 inch
5. Whipstitch around the edge:
- Bring needle up through garment, catch patch edge,
push back through garment
- Repeat every 1/4 inch around the perimeter
6. Best for: jeans, jackets, work clothes
CODEBLOCK4
HEM PANTS OR A SKIRT:
MEASURE:
1. Put the garment on with the shoes you'll wear
2. Fold the excess fabric under to the desired length
3. Pin in place
4. Take the garment off carefully
PREPARE:
1. Measure the fold-up amount — it should be even all the way around
2. Mark with chalk or pins every 3-4 inches
3. For pants: standard hem allowance is 1.25 inches folded under
4. Cut excess fabric, leaving 1.25 inches below your desired hemline
5. Fold raw edge under 1/4 inch, then fold up to the hemline
6. Press with an iron to create a crease
SEW (blind hem stitch — invisible from outside):
1. Thread needle with matching thread, single strand, knotted
2. Working from inside the garment:
3. Catch 1-2 threads from the outer fabric (barely visible from outside)
4. Then take a small stitch through the folded hem edge
5. Repeat every 1/2 inch
6. Keep stitches loose — pulling tight creates puckers
7. Knot off inside the hem fold
NO-SEW OPTION:
1. Iron-on hem tape (Stitch Witchery or similar)
2. Fold hem to desired length, press with iron
3. Insert hem tape between the layers
4. Iron with steam for 10-15 seconds per section
5. Let cool before moving
6. Note: this may not survive multiple washes — resew eventually
CODEBLOCK5
ZIPPER FIXES BY PROBLEM:
ZIPPER WON'T CLOSE (teeth separate behind the slider):
- The slider is worn out — teeth are fine
- Fix: Use pliers to gently squeeze the slider slightly narrower
from top and bottom (very gentle — too much cracks it)
- If that doesn't work: replace just the slider (buy a matching size
at a fabric store, $2-3; slide off old, slide on new)
ZIPPER IS STUCK:
- Rub a graphite pencil along the teeth (the graphite lubricates)
- Or rub a bar of soap, candle wax, or lip balm along the teeth
- Work the slider back and forth gently
- Check for fabric caught in the zipper — pull fabric taut away
from the zipper while moving the slider
ZIPPER PULL BROKE OFF:
- Thread a small key ring, paperclip, or safety pin through the
slider's pull tab hole
- Works permanently — doesn't need a real fix
WHEN TO TAKE IT TO A TAILOR:
- Full zipper replacement (teeth are damaged or melted)
- Zipper on a coat or dress where appearance matters
- Cost: $10-25 for pants, $30-75 for jackets depending on complexity
CODEBLOCK6
STAIN REMOVAL BY TYPE:
RULE #1: Treat immediately. Old stains are 10x harder to remove.
RULE #2: Always blot, never rub. Rubbing spreads and pushes the stain deeper.
RULE #3: Test on a hidden area first (inside seam or hem).
GREASE/OIL (food, butter, salad dressing):
-> Apply dish soap (Dawn or equivalent) directly to stain
-> Let sit 5-10 minutes
-> Wash in warmest water safe for the fabric
BLOOD:
-> Cold water ONLY (hot sets protein stains permanently)
-> Soak in cold water, rub with hydrogen peroxide
-> For dried blood: soak in cold salt water 2-4 hours
RED WINE:
-> Blot immediately (don't rub)
-> Cover with salt to absorb
-> Pour boiling water through the stain from 12 inches above
-> Or soak in a mix of dish soap + hydrogen peroxide
COFFEE/TEA:
-> Flush with cold water from the back of the stain
-> Apply white vinegar, let sit 10 minutes
-> Wash as normal
INK (ballpoint):
-> Dab with rubbing alcohol using a cotton ball
-> Place paper towel under the stain to absorb
-> Repeat until ink stops transferring
-> Wash as normal
SWEAT YELLOWING:
-> Mix 1 part baking soda + 1 part hydrogen peroxide + 1 part water
-> Apply paste to stain, let sit 30 minutes
-> Wash in warm water
CODEBLOCK7
IRONING BASICS:
TEMPERATURE BY FABRIC (low to high):
- Synthetics (polyester, nylon): LOW heat, no steam
- Silk: LOW heat, press cloth between iron and fabric
- Wool: MEDIUM heat, steam, press cloth
- Cotton: HIGH heat, steam
- Linen: HIGHEST heat, lots of steam
TECHNIQUE:
- Iron clothes slightly damp or use the steam function
- Move the iron in smooth strokes, not circles
- For dress shirts: collar first, then cuffs, then sleeves,
then back, then front panels
- Iron on the WRONG side (inside out) to prevent shine on dark fabrics
- Hang immediately after ironing
HAND-WASHING DELICATES:
1. Fill a basin with cool water
2. Add a small amount of gentle detergent (Woolite, or a few drops
of dish soap)
3. Submerge the garment, gently swish and squeeze — don't twist or wring
4. Let soak 10-15 minutes
5. Drain, refill with clean cool water, swish to rinse
6. Repeat rinse until no soap remains
7. Lay flat on a clean towel, roll up the towel to press out water
8. Reshape and lay flat to dry (never hang wet knits — they stretch)
HAND-WASH THESE:
- Anything labeled "hand wash" or "dry clean" (many dry-clean-only
items can be carefully hand-washed — silk and wool especially)
- Bras (machine washing destroys elastic and underwire)
- Cashmere, merino wool, silk
- Anything with beading, sequins, or delicate embellishment
CODEBLOCK8

操作指南
第一步:准备基础针线包(15美元)
代理操作:询问用户是否有缝纫用品。如果没有,生成此清单。以下物品在任何布料店、一元店或网上均可买到。
基础针线包——总计约15美元
必备品:
[ ] 手缝针,混合尺寸包(2-3美元)
- 5-10号尖针用于一般缝纫
- 一根大号针(绣花/织补针)用于厚面料
[ ] 缝纫线:黑色、白色、深蓝色,以及与你最常穿衣物颜色匹配的线(4-6美元)
- 涤纶通用线适用于所有面料
[ ] 直针(1-2美元)
[ ] 小剪刀或线剪(2-4美元)
[ ] 拆线器(1-2美元)——用于干净地拆除旧针脚
[ ] 软尺(1美元)
[ ] 混合纽扣包(1-2美元)
[ ] 熨烫式裤边胶带(2-3美元)——应急用免缝改边
[ ] 安全别针,混合尺寸(1美元)
加分项:
[ ] 顶针(保护手指在推过厚面料时)
[ ] 布料粉笔或可水洗标记笔
[ ] 蜂蜡(将线穿过——防止打结)
第二步:缝纽扣(10分钟)
代理操作:这是最常见的衣物修补。慢慢引导——大多数人从未穿过针。
缝纽扣:
穿针:
- 1. 剪下24英寸长的线
- 将线的一端穿过针眼
(如果穿不过去,将线头沾湿并捏扁)
- 3. 拉过直到两端等长
- 将两端打一个双结系在一起
(用双股线缝纫以增加强度)
定位纽扣:
- 1. 找到纽扣原来的位置(寻找线头残留或痕迹)
- 将纽扣放在布料正面的正确位置
缝制:
- 1. 从布料背面将针向上穿过一个纽扣孔
- 将针向下穿过对面的孔,再穿过布料
- 每对孔重复4-6次
- 对于四孔纽扣:缝成X形或平行线
(与衣物上其他纽扣的图案一致)
制作线梗(适用于外套等非扁平纽扣):
- 1. 最后一针后,将针从纽扣和布料之间穿出(不穿过孔)
- 将线在纽扣下方的线束上缠绕5-6圈
- 这形成了一个梗,为纽扣洞的布料层留出空间
收尾:
- 1. 将针推到布料背面
- 缝一个小针脚,将线穿过它两次打结
- 拉紧,剪断线
- 完成。总时间:5-10分钟。
第三步:修复开裂接缝(10分钟)
代理操作:这是第二常见的修补。开裂接缝通常发生在受力点——腋下、裆部、侧缝。
修复开裂接缝:
识别问题:
- - 接缝开裂意味着线断了,而不是布料破了
- 布料边缘完好,原始针孔可见
- 这是最简单的修补——你只需重新连接两个边缘
使用回针缝(最强的手缝针法):
- 1. 用匹配颜色的线穿针,双股,末端打结
- 将衣物翻到反面
- 在开裂处前1/2英寸开始(与现有针脚重叠)
- 从背面将针向上穿过布料
回针缝技巧:
- 1. 在出线点后方1/8英寸处入针
- 在出线点前方1/8英寸处出针
- 将针插回上一个针脚结束的位置
- 再次向前1/8英寸出针
- 重复——每一针先向后,再向前
- 继续缝到开裂处末端后1/2英寸
- 在内部打结收尾
为什么用回针缝:
- - 形成连续的针脚线,没有间隙
- 比平针缝更强韧
- 从外部看几乎与机器缝纫无异
第四步:补洞(15分钟)
代理操作:方法取决于洞口大小和衣物类型。在进行前向用户询问这两点。
按洞口大小的补洞方法:
小洞(小于1/4英寸)——织补法:
- 1. 用匹配颜色的线穿针
- 在洞口上缝制细小的平行针脚
- 然后垂直编织针脚穿过它们
- 你正在创建一个微小的布料网格来填补空隙
- 最适合:针织品、毛衣、袜子
中洞(1/4英寸至1英寸)——熨烫式补丁:
- 1. 剪一块比洞口四周大1/2英寸的熨烫式补丁
- 将衣物翻到反面
- 将补丁胶面朝下放在洞口上
- 用中火熨烫30-45秒,施加稳固压力
- 完全冷却后再移动
- 最适合:牛仔裤、棉布、帆布
大洞(超过1英寸)——缝制式补丁:
- 1. 从匹配或互补的布料上剪一块补丁
(旧牛仔裤、头巾等)
- 2. 剪一块比洞口四周大1英寸的补丁
- 用别针将补丁固定在洞口上
- 将补丁的毛边向内折1/4英寸
- 沿边缘进行锁边缝:
- 将针从衣物穿出,钩住补丁边缘,再穿回衣物
- 每1/4英寸重复一次,围绕整个周边
- 6. 最适合:牛仔裤、夹克、工作服
第五步:改裤子或裙子边(20分钟)
代理操作:改边是大多数人花钱找裁缝做的修补(10-25美元)。自己做其实很简单。
改裤子或裙子边:
测量:
- 1. 穿上衣物和你要搭配的鞋子
- 将多余布料向内折到所需长度
- 用别针固定
- 小心脱下衣物
准备:
- 1. 测量折叠量——应全程均匀一致
- 每3-4英寸用粉笔或别针做标记
- 对于裤子:标准折边余量为向内折1.25英寸
- 剪掉多余布料,在所需折边线下留1.25英寸
- 将毛边向内折1/4英寸,然后向上折到折边线
- 用熨斗熨出折痕
缝制(暗缝针法——从外部看不见):
- 1. 用匹配颜色的线穿针
