Only I didn't have 48, there were only 46, I don't know where the other two went but I had to make up two more from the scant scraps that remained. The fabric given for this block of the month is not generous. I already had to beg some extra blue from my friend (luckily she has an amazing stash!) for the pinwheel triangles.
The final result is 2 18.5" blocks.
Despite the hassles this is my favourite block so far.
