I wanted to mention something about the blocks being cut on the bias.
Three years ago, I made a string quilt that was cut on the bias, and did not want to match any of the stripped seams, so I simply starched the snot out of my strips before cutting and everything turned out fine.
I'm currently making a quilt with blocks that are cut on the bias, and this time I AM trying to match the seams. Because the blocks are cut on the bias, it's a little tricky, but then on the other hand, because the blocks are cut on the bias (ha ha), it's easier to ease in and finesse the seams! I've had to stretch some parts, and that results in a horribly wavy seam, but because it's on the bias, when I steam and press the seam it settles down beautifully. I get a wonderful, flat block with matching seams.
