Just Jan,
The border on Constellation is 1 1/2" unfinished, with 1 1/2" unfinished cornerstones.
The blocks finish at 10". Basically, they are using 2" size pieces, HSTs, etc. (finished). So, Constellation, finished, is 8" in the middle, with 1" border to make up the 10" block. Whirlpool is the same. Double X has a 6" middle and a 2" finished border.
