2 €, second hand. I washed it first.
Get a shirt that suits you well and start with the sleeves. Lie it on the jumper and draw a line around the perfect sleeve onto the big sleeve. Sew & cut excess fabric
Do the same with both side parts. Make sure your seams are clean and straight as it will affect the look when wearing it: Wrinkles, too much space, too tight parts etc.
finished!
