I found it!!! I knew I'd find it in the end. This time it wasn't lurking under the scanner but under a pile of paperwork on my computer table! Who sends in the gremlins to do this to me? OR is it one of you 'lot' out there in cyberspace? Bet it is. Somebody must be breaking into the house while I'm asleep. That's what's happening.
Anyway, here are four of the squares joined together. I love the centre pattern that they give. Maybe I'll do another set of four - or more. Just to see what they look like in other colours!!!
