Craft stall items

I'm making coffee cup coasters for a stall at a craft fair. I have no idea if they'll sell, but it is a quick and easy pattern and looks quite effective. I've been doing them in sets of 2 and without realising it, I've done them in 2 sizes. (I thought I'd been using a size 4 hook but it had been a 5mm so when started again, I had 2 sizes!)
