I finally got around to making Starboy's new PJs, and a bib to match. "I'm all mouse!" He proclaimed.
The fabric is Heather Ross' Nursery Versery Country Mice (Kokka Fabrics/Japan). I was wondering why it was so lovely to work with — turns out it's not 100% cotton after all, but 85% cotton and 15% linen! YUM.
The pattern is an Oliver+S PJs pattern, for size 5. The pants have to be rolled up twice, but he should get a lot of wear out of them.
