When I found a silky Fancy Nancy remnant at Jo-Ann, I couldn't resist making something for my little Fancy Lou. Of course, this sort of fabric (although "not to be used for children's sleepwear," since it is not doused in flame-retardant chemicals) is best suited for around-the-house apparel. Pajama bottoms!
I followed Dana's Kid Pants post and traced another pair of Louisa's pajamas that fit her well, but it turned out pretty wonky. I had little patience for perfecting the pattern after making a trial pair from an old pillow case.
