I'm not able to post pictures, Woody. I know i screwed up a few blocks trying to "trim" the corner triangles to match. my seams do match up but the points in the middle wind up being of various sizes...usually too small. When i diagonally cut my big square units into quarters, i notice the triangular tips that form the square are not the same size. the strip that forms the square was cut at 2.5" all the strips measure 2.5" and the seams are accurate. I use a guide to cut from one diagonal corner to the other. I feel this just has to be the step that is causing the problems? some triangular points are quite a bit smaller than others! at this point, i'm just hoping to get enough "good" points to have enough blocks without buying more fabric. it kind of defies logic how equal squares can be diced into unequal parts!
