The TAST stitch for week 46 is checkered or magic chain. I learned this stitch in 2011 when I was catching up on the last TAST 2010 stitches. I made one big sampler and tried all stitches at the edge first.
Then I mixed them with the other TAST stitches. Here I ended the magic chain with pistil stitches.
It seems this was the only time I used this stitch. I hope to find the time to experiment with it this week. Mary Corbet’s video could be a great help if you have trouble with this stitch.
