I wonder why they named it that? I don't know, but I like the block! And may I just say I love starch? I forgot to use it on my first block, and it had a few places that I had to do over a couple of times... I remembered to use starch this time and this block just flew together so easily. I worried as I measured it (don't you always?) but it is 16 1/2"! Yay, 2 blocks the same size, I hope I can do that a few more times!
