I'll just say from the start, that sometimes it's hard for me to stop once I start making kids' clothes. There. I said it.
Actually, this was the first idea in my mind when I realized that I would need to make all of my Christmas gifts if there were going to be any gifts for my family and close friends. Thankfully, when my mom sent me this pattern, she made sure to purchase both the adults and kids' patterns. Now, I don't know about you, but I love me some lounge pants and I'm hoping my goddaughter likes them too.
Pam at Fashion Sewing Supply and it's fabulous. It will stretch for days and days and days. I definitely recommend her elastic. It's the best (as is her interfacing!).
