Thanks for all the compliments!
The outer 20 blocks are now part of the center unit. I would be posting a pic, but the darn wind is really blowing, so I can't get one right now. Maybe it will settle down before it gets too dark to get one.
I have cut & marked the next shark tooth border pieces. Now I need to sit with the iron & press all the points. When that's done, I'll start to put them on the background. I don't remember if I basted the points down or not & I didn't put that bit of info in the tute I did - figures!!!
