I used WDW perle #5 in Periwinkle and Caron Wildflowers #6033 I think. The horseshoe stitches aren't as flat as I'd like, but I'm okay with them overall.
The original chart has beads as you can see in Mabel's original design:
Since I plan on making this into a lap rug/afghan I didn't think beads were a good choice for comfort and I stitched Greek crosses on mine instead.
We've been re-watching the Back to the Future series when it showed up on Amazon Prime recently and finished BttF II last night. I managed to start August SOTW which has a complicated pattern of Kloster blocks, but I like stitching Kloster blocks, so it's been fun. The center has an interesting design and I hope I can make mine look as good as the others you can see in the SAL gallery.
Here's my start with Caron Watercolours Abalone:
Mabel is planning a 2016 SAL, Round in Circles, and I'll be signing up for that one in December when she opens it up. I have lots of thread left from this one and I'm looking forward to continuing on with hardanger for occasional stitching.
If you have any interest in hardanger Mabel gives great instructions on the new stitches and I've enjoyed learning them, so 2016 may be your year to try it out. :)
