Obviously these twins need some nightclothes, right? :) I made both of their pajamas from a remnant of yellow fleece I picked up at some point. I think it was 1/3 yard, but I can't remember for sure. At any rate, it was just enough. I didn't have a scrap left!
These were made with the same pattern as the camo pj's, Simplicity #1952. I love this pattern! The only thing I would recommend is that you cut the neckband (the facing) twice as long as it shows, since the only fabric I've ever worked with that stretches that much is a knit.
If you have this pattern, or if you've seen it, you know that there is no nightgown pattern. For fleece, I didn't want anything with gathers anyway, so I simply lengthened the shirt pattern to the length I wanted it. Now they have matching jammies.
Both of these have back Velcro closures, which I highly recommend for children. Buttons can get fiddly, and zippers can pinch fingers (and dolls' fabric bodies).
I hope you're enjoying my Bitty Twins fashion show because there's lots more to come! :)
