I've been reading the site for a while now, but this is my first post as I haven't actually completed any retro projects. I did manage to find this great sewing book a few weeks back at my local second hand shop.
It has great information on everything from planning, drafting patterns, choosing your fabric to refashioning and repairing existing clothes.
I really like the simplicity and thoroughness of the instructions.
If you like the Vogue cape pattern in the recent post this might come in handy... (hopefully the picture is clear enough!)
