After I bought some footie pajamas last year, I found that I liked footies so much that I wanted to make some myself... so finally I did, and this is the result. I think they turned out pretty well, considering that I had only done small repairs or alterations up to that point, and I only had a cheap $89 Singer from walmart to work with. I have three more patterns I've cut out, but not assembled yet... Anyway, the zipper goes down to right above the knee, and it has a butt-flap and pockets as well. The cost for the materials (3 yards of fabric, zipper, snaps, thread, etc) was about $28-$30 (Retail). Kinda expensive, but it's not too bad I guess... I get to pick the fabric I want, so that's cool. They took 5-8 hours to make each, depending on how many mistakes I made (and there were a few mistakes).
So here's a view of the front---
And a view of the back showing the butt-flap. (made with elastic and five snaps)---
Yep, monsters and dinosaurs. I like 'em. :P
