Two months have passed. I forgot to post a photo of April's block ... Brasstown Star
The block I chose for May was Beacon Lights, which gave the option of regular piecing, or paper piecing. I chose regular piecing even though I had to add seams to the pattern pieces.
It wasn't until I had completed the block, and measured it, that I was happy in the realisation I had worked out the sum correctly!
My camera isn't picking up the colours all that well. The spotty fabric is actually a rather rich cream, and the flowery fabric has pretty mauve flowers on a greyish background.
