Four weeks was enough during May to get my block completed. I kinda lost steam this past week; I think, partly because mentally, I felt like I had done as much as I wanted to the block. I'll add the Knotted Cretan to the June block. This is the last block of the orange and yellows. June's block starts the group of green blocks. I think by the time I got to this yellow block I was getting bored with the whole red-orange-yellow group. The nice thing about this challenge is that the color changes at each month!
