I just made a bunch of those blocks and it had me cut a 4 7/8 block for a 4.5 unfinished block. Doesn't seem logical does it? If you use the Deb Tucker Tucker Trimmer ruler, she says to cut .5 larger than you need and then trim it to size after stitching together. As I tend to not stitch a straight line I think I'll use Deb's method the next time and to heck with wasting a little extra fabric.
