I bought this fabric and half past four and had the pinafore done by half past seven... it's a bought shirt though (co-incidently bought at the same place I got the fabric, I just realised).
I made the pattern from a 'sloper' a couple of years ago, inspired by a wonderful 1950s Vogue sewing book. (the red is the first fabric I made it from - a lovely wool woven with lycra)
As may be obvious, I do love a pinafore!
