The kids always get Christmas pajamas from St. Nick, and this year I decided to help him out a little by sewing up some coordinating fleece jammies.
O's are medium pants from Kwik Sew Sewing for Children. I widened the legs by 3/4" at both edges and eliminated the side seam. You really can't go wrong with the basics from Kwik Sew.
I was more ambitious with E's and went for footie pajamas. I picked up the Peek-a-Boo Classic Footed Pajamas pattern on sale a bit ago with these PJs in mind. The description says, "New to sewing? No problem", but I would suggest that you not attempt these until you're pretty comfortable with clothing construction. There are some pieces that are a bit awkward to put together, and the most potentially confusing part of the zipper installation doesn't have a picture or diagram in the instructions.
They went together fairly smoothly, although they did take longer than I'd hoped. I was pretty crabby about them for a while yesterday, but now that they're done and I saw them with O's, I'm pretty pleased. I cut a 4T width and 5 for length. She hasn't tried them on yet, but they seem similarly sized to RTW pajamas.
Do you celebrate St. Nick's Day where you live? In the U.S, it seems to be limited to very specific geographic areas. It wasn't a thing people did in my hometown, but here on the other side of Wisconsin it's very common.
