Don has been hanging prisms in our great rooms Southeast facing window. The resulting splashes of color are beautiful! They bounce around, too, when we have fans circulating air......spectacular!
Right now, he only has hung 5 in the great room window, but has more available. We have 1 window in the loft that faces the same direction, so perhaps he'll hang a few there, too. Then there are the "mostly" South facing windows........oh the possibilities! ;)
