This was my original block plan. I'm thinking now though, that it is too busy. I'm working on a simpler version though, one that has some background fabric. If I spread out the four rows with predominant background fabric, I think that will balance things better.
Here's my fabric, and my original plan.
This is the new block I'm going to use instead. It is a variation of a hopscotch block, or a variation of a shoofly. I'm not sure if it has a name. I'll work on the tutorial as soon as LAX is over (DH out of town again). For now though, the corner units are 4 inch half square triangles, and the cross units are from 2.5 inch strips. More to come.
