What you will need:
For this project, you will need the following items:
- A jean jacket or vest
- An old sweater (preferably with sleeves the same size or slightly larger than your jacket or cardigan)
- Thread
- fabric scissors
- Sewing machine
- sewing pins
As we just mentioned above! For added comfort, it’s best if the sleeves of your sweater and jean jacket are similar in size. If the sizes don’t match, you can wear sweater sleeves with larger shoulder openings than the jean jacket. In fact, it’s easier to shrink than expand a garment, you can simply stitch along the side of the sleeve to adjust the size as needed. Up to you !

The steps to follow:
If you want to add sleeves to a cardigan or jean jacket, there is no shortage of tips! But in our opinion, the easiest way is to turn the jacket inside out and fix the sleeve to the armhole. Follow our guide:
- Turn your jean jacket inside out and use your scissors to cut the sleeves, leaving about an inch past the shoulder seam.

- For the sleeves of your sweater, do the opposite, the cut should be made a little further from the shoulder seam (to give you a longer sleeve).

- By leaving enough fabric, you will have enough room to sew the sleeves of your sweater to your jean jacket.
- Before sewing anything, make sure you line up the shoulder seams before pinning (turn the jacket inside out to check if the sleeves fit snugly around the shoulder. This is to ensure the end result is comfortable and stylish ).
