My daughter bought a school tshirt. It was a size S but it was too big at the shoulders and too long for her. She asked if I could fix it. I got really ambitious and managed to convince her to let me cut up her brand new tshirt :) I cut off the sleeves and adjusted the armhole higher up the shoulder seam and re-sized sleeve cap following one of her fave tshirts. I also took in the sides and re-shaped it like her fave tshirt which has a gentle girl-cut waistline.
I managed to put it back together!!
I had trouble hemming the bottom of the tshirt. In the end, I used this tape and sewed it over the raw edge of the hem.
I sewed 2 rows of stitching to mimic the 2 needle seam of the original hem.
Everytime she wears this tshirt, I'm going to smile to myself. I did it! I re-sized her tshirt!
