Mine goes into an RV. So I'm going to try to put a rubber band over two rows of spools, two per side, total 8. Should keep the spools on even if turned over.
Interesting the comment about the hinge...first thought when I held it was....Hmmm if it was hinged on the side you could put sparkles on the inside. One corner hinge with the latch? on the diagonal on the bottom, a few cuphooks on the inside walls.
Course we'd tinker with anything....never sated.
