Addendum

    This is sort of an add-on to my post earlier today.  I have a couple of local art festivals coming up, so I may not do any blogging for a few weeks.  So I thought I'd take a quick picture of the straight, but spiraled string of tetrahedrons I came up with.  I think it's kind of cool. 
    By the way, thinking of festivals, if anyone will be in the Chicago area, I'll be showing my jewelry at the Highland Park (northern suburb) Festival of Fine Craft the last weekend in June.
