OBMQ HQ (!), so I felt I simply had to find something to post. :-)
Although I was out of town most of the weekend, I managed to get a few of the red strippy triangles created last evening. See those two right in front? They were the produce of my first square, cut in half the wrong way. Uh-huh. In my eagerness to get 'em started, I forgot that the plan is to cut them across the strips, not with them. Sigh.
"Quilt in a Day" ruler from the wonderful Eleanor Burns. (Note to Self: go to this site and take the tutorial!) Once I have my 5 1/2" block trimmed and sliced the right way, I use this ruler to trim each triangle down to 5 1/8". I'm thrilled about this, because for a few minutes last evening, I was standing on my head trying to do the math in order to square it up with my conventional ruler. I think I could have done it, but this has proved less painful (and no, I'm not buying any more rulers till I'm sure I need them!) :-)
