I’ll admit it; I love cardigans. I love cardigans on myself, on little boys, and especially on babies. I had some girly cardigans in my stash that needed to be made into baby onesies for Claire, so I made a free pattern and tutorial for you to make your own onesie cardigan! It’s even a simple and quick gift to make for baby shower gifts!

7.  Sew single fold bias tape onto the leg openings. If you want it to show, sew it on the inside first. Then fold it towards the front and sew close to the edge. If you don’t want it to show, sew it on the outside first. Then fold it towards the inside and sew close to the edge.

8. Insert 10″ of elastic into each leg opening tacking at the ends.
9. Use the bias tape to finish the edges of the crotch. When you sew it on, fold the bias tape around the edges to give it a finished edge.
10. Attach some snaps or add buttons or buttonholes!
