My mum was telling me about Clothkits. She used to get them mail order when we were children. They were basically sewing kits which had everything you needed to make items of clothing - the pattern to cut out was actually on the material.
I am interested to find out if they still exist. I have been trying, and failing, to find the perfect dungarees for ds2 who is in cloth nappies, and thought it may be easier to make my own.
