I couldn't show one sister's refashioned shirt
Kwik Sew 2555 for both.
When I helped my mom move, she gave me a bin of over two-dozen event t-shirts collected over the past 20 years. I sewed them up into about ten long-sleeved t-shirts, using one shirt for the body and another for the sleeves.
I've collected* 51 women's Kwik Sew (KS) patterns and only used four of them so far. However, I used Kwik Sew 2555 27 times (since I began record-keeping 5 years ago). I have used three of the ten Kwik Sew children's patterns in my collection. However, I've sewn dozens of things from the Sewing for Baby, Toddlers and Children books.
* I didn't purchase all of them. Whenever people give away old KS patterns, I scoop them up.
