Tartan - good idea! I'm going to applique the blocks on, so will definitely put another layer under the fabric.
Platyhiker - thanks for that thought about the light ... hadn't thought of that at all, and will definitely move them around. As for the tiny dots in the middle, I admit, I cracked up laughing, because those are pins LOL ... BUT, I like the idea, and will see what I can come up with.
Thanks all for the comments, border is going to get sewed on and backing and applique put on blocks and we'll see what happens next!
