I'm a bit mad with myself about the tape measure because I was looking for a cheap one to use and found one for 79p in B & M Bargains which I think is pretty good for a five metre tape but thought it was a bit wide for this project so I decided to use a small one that I keep in my handbag for when I'm shopping.

I've put a sewing tape in but of course that's a lot shorter and it's not much good for measuring large things if I'm on my own because it's too floppy.
