I played with this template last nice. Made my own template, traced it off on printable velum. Did the 1" in the one corner 3/4" in the other three. First one, first time laying it on my squares, the cross lines didn't line up. So, I walked away for a bit, to think about it. Then, the thought occurred to me, try another ruler! So, I did that, made another template, & they lined up! Now, I did try 3/4" in all four corners, & that didn't work, once I changed one corner to 1", then it all lined up. I have my pinwheels cut now & ready to stitch together, & I used 30 blocks, 5 rows of 6, then added a 3" border... Will share a pic when I get it all sewn together. Still thinking of a border too...
