It works up pretty fast and I'm enjoying doing it, but really, I don't see a lot of impact on all that backwards movement of stitches. Because it takes 2 double-crochets to make each cross-stitch the second one is always made in the hole you skipped over - making you go backwards. I don't know... maybe it's because my yarn is so dark that I'm not getting the full impact.
Of course, I'll give it another try! Like I said, it's a fun stitch that's easy to do and works up pretty fast. I don't use the large hook too much, but it seems perfect for this endeavor.
