woohoo! I've been stalling getting that mostly white, modern quilt on the frame--worried about how to mark it, etc. Well, spent the morning marking with chalk, figured out that my Gammill ALREADY had a black light installed --just needed to flip a switch--duh! And can see the chalk just fine with black light. So have it on the frame with double wool bat--plan to do a lot of quilting and wanted some pouf--and have it about half way stabilized. It's working! So excited and little embarrassed that I was too chicken to get this project going!
