Tools needed: cuffs, needles and threads of old sweaters.
1. Cut the elastic cuffs of the old sweater first.
2. elastic belt cuffs are inserted into down jacket cuffs and arranged neatly.
3. After the seam is neat, sew a circle along the seam.
4. When the needle is inserted into the down jacket, the thread is longer, so that both the needle and the thread are left inside, which is very beautiful.
5. The outer sewing of down jacket should be as short as possible, also for the sake of beauty.
6. You can sew a circle, open the cuff, and you can see that there is still a needle and thread inside.
7. After doing this, the effect is quite good. Sleeves are lengthened and cuffs are locked.
Note: don't throw away the old sweater after use, keep it for other purposes, and pay attention to saving.
