I don't like block 3 as much as 1 or 2. So far out of the bigger blocks #1 is my favourite.
I have also made block 15 -
And 16 -
I quite like them both. 16 was super quick to whip up. It is weird though because from the dark and dotty blues you have to cut a 13.25" square which you then cut into quarters. Am I going to use the other three cut quarters somewhere else? If I am not, why couldn't I cut a smaller square in half? Anyway, I made another block using some of the left over triangles from this one -
And given I still have two giant triangles cut, I might make more of these blocks in place of some 6" blocks.
