No worry, Rita... "again, again, again" is no problem for me since it translates into "practice, practice, practice!"
It's funny, I was really tempted to draw the circles into the squares but decided not to because I probably would not be able to follow the line anyway
but I discovered that once the first set of circles were done (the hardest part), then if I just looked ahead at the next intersection and did somewhat of a curve in the direction of that next point (you know, don't look at the needle, look at where you're heading), it started being more fun (and even a little more successful, even if still wonky). Rita, you HAVE TO TRY IT! It's FUN! (look who's talking, right?)
Michelle, you and others who commented are right--deep down I know it. I need to get this onto a quilt. I kind of had it in mind for my Chinese round robin quilt, Rabbit in the Moon, and that is why I was practicing it. Even though we call it, among other things, a pumpkin seed stitch, in the Japanese sashiko world, it is known as Buddha's Seven Treasures. So I thought, wouldn't it be fitting in some of the light beige spaces of that quilt. I had not thought beyond King Tut 40 wt. but I think you are right about a light weight thread. How about Aurifil 50 wt.? I have a color that would match the fabric.
