I am not a sewing buff, but I do try to sew once or twice a year in an attempt to improve myself. I found this great tutorial on U Create and just had to try it. It was created by Char and I did option 2 since I don't have a machine that can serge.
This is my friend's daughter who is just learning to walk. The onesie was a little too big for her, but you get the idea.
So cute and the best part is that she has some skirt/ruffles in the back but can still crawl with ease. I'm happy with my first attempt and ready to do some more!
