I'm currently working on a 3D pinwheel block. For the pinwheel I basted the squares together before sewing because I just knew they'd give me some problems if they were only pinned. I'm pleased with the result. If I make one only I shall turn it into a candle mat but if I go ahead and make the other there will be a pair of mug rugs, I think.
Interesting colour differences - the
truer colour is the bottom photo.
