A useful source could be this magazine I bought for a few pence from a charity shop.
First of all of course there's all the equipment needed.
Just follow the instructions and a few hours later you too could be the proud wearer of one of these fab outfits...very 1970s!
The magazine is dated 1973. Despite that there's loads of useful advice...if I ever decide to take up crochet again, I'll be reading this first.
A few more fun purchases - a couple of remnants of fabric, one Sanderson from 1981, not sure about the other, and loads of buttons. Noreen gave me some of these...can't wait to use them.
