As I can't work on or show you a finished garment, I thought I'd show you my vintage pajama pattern collection:
The bulk of the older patterns shown above were bought as one - they were all squished into a manila envelope in the "craft box" at one of my local second hand shops. A crappy old envelope sounds like a terrible way to treat delicate patterns, but they were definitely better off in that envelope than being loose in the craft box with other patterns, knitting needles etc. The one exception to the manila envelope rule is the 1920s women's pajamas which I couldn't resist on etsy.
This sweet pattern was also shoved in with all the pajamas:
The more recent patterns were separate but mostly bought at the same place, same time or soon after. They were certainly very cheap - but I do NOT need any more pajama patterns.
