My mum used to make a lot of our clothes when we were kids.
She used to think it was cute to make matching outfits for my two brothers which wasn't too bad - there only a couple of years apart
Ufortunately she used to matching dresses etc for my sister and I too; I'm seven years older, practically a lifetime and I HATED it!!!

When you're 13 you don't want a dress with orange and yellow daises and lace round the neck and collar! Oh, I was so hard done by!
She made her own patterns by copying the clothes they already had. She used to buy things from jumble sales (not seen one for years - where have they all gone?) for the fabric or buttons or use hand-me-downs and remake them into something else. Not always clothes - she used to make ragdolls from cotton fabrics and teddies from fake fur coats.
