This is happening, just in time for weekend sewing. Most quilts start this way for me. A block idea pops into my head. I decide generally how big I want the pieces to be, and then I just see how big one block turns out. No math. Forget it. I know, I know, I work backwards, but I just like the results of doing it this way better. Being responsive instead of planning too much allows me to make decisions visually and aesthetically rather than analytically. I guess I just like to keep things loose as I piece.
