I've done some serious pattern shopping on eBay! Over the last month I bought three lots of vintage children's patterns plus a few individual patterns.
I don't know if I'll be able to sew any of them. My daughters aren't nearly as into the patterns as I am and then there's the time factor. But I do enjoy shopping for them and they are just a great piece of the past that I enjoy having and sharing with my kids to see what would have been different if they had been born 40 to 20 years earlier.
