OK, so thes are my clones samples.  The top one is using yarn and was pretty good so tried thread, however
not very even and very difficult to use.  I always have problems with this thread, don't know why I don't throw it out.  The bottom sample is using much better thread and I am very pleased with the consistency and the ease of use.

you think I would learn, using the rotten thread here are my roll stitches.  Not very good.  will try with better thread.
