How else? The plastic is quite thin.. maybe 1/32 of an inch and more like saran wrap than Plexiglas. It is not hard, and not rigid. The stuff is cheap, so buy spare and try it...... You have one more possibility..... a 4 sided mask... Make the mask from 4 sheets of rubylith that are butted together.... and use a top sheet as a "glue binder" sheet. You tape the 4 sheets to the top sheet to hold it all together. Try it with paper first to figure out how to do it efficiently.

One more question regarding using the ruby lith as a mask: does one cut it freehand, like a window mat (I was never much good at doing those...)? Any additional suggestions appreciated! Rita
