Have you visited http://www.vintagepatterns.wikia.com/? It's like an encyclopedia of patterns and the wiki bit means anyone can add pages.....it's mucho fun.
On sewweekly Kat is currently organising a pattern swap. The idea is you sign up, then Kat will randomly assign each person a "sender". You are told who you are sending to, you send a pattern and wait for your parcel to arrive.....
That was a very long-winded way of saying I have been sorting through patterns.
Mostly because I wanted to see what goodies I had to send another sewweeklier. But also for my FESA challenge and because I needed a skirt pattern. Conclusion: I have too many patterns.
I've picked out some interesting patterns from the pattern mountain and been on the pattern wiki to see what I could find out:
I have 2 more older looking patterns, but neither are on pattern wiki.But I have played Sherlock and this "brunchcoat" is dated 1952 (OK, it says so on the packet)
Finally, no clue on this Simplicity S 19 pattern, how old do you think it is?
