This is why I don't sew when I'm tired. A LOT of HST. Drew a line down the center, and sewed 1/4" on one side of that line. Turned the blocks around and proceeded to sew right down the center penciled line. Oops! I got the seam ripper and was just about to start taking that center line stitching out when I occurred to me that I didn't have to. Those would be cut apart on that line. So back to the sewing machine to sew 1/4" down the other side of the center line.
I think that's as far as I'm going tonight. Not an hour of sewing. 25 minutes of doing the oops-dance! I'm going to bed!
