At the beginning, I did it wrong, trying to make it a normal chain variant. Then I learned and explored its usefulness for formal bands. During the first few rows I tried it as a regular chain stitch variant.
Then, I tried to do it in a more random way. I was not entirely convinced. But this did get my imagination going. how about doing this as bark of a tree?
The next sample was about as random, only I used wool thread that gives a good coverage for most of the ground stitches. I like this much better, although the first random version is probably better for bark.
