Anyone have any good ideas for making homemade molds for shades etc that
will last and can be reused? I would like to make some items in odd shapes
for lamps, etc., but want to be able to reproduce them if I like the final
result. Would styrofoam hold up to multiple uses? Is it tolerant of the
heat generated during soldering? Or will it melt in an awful mess? Any
comments are appreciated!
