Twisted tin icicles can be very effective on a Christmas tree. These may remind you of vintage icicles, but they are carefully crafted for modern customers by Kevin Burgess and Drew Coduti of B-C Designs, a fine local New Mexico studio. The icicles come in a package of thirteen. Several packages will do a tree nicely. The icicles are easy to use because they are curved at the top to put over a tree branch. They are about six and a half inches long (16 cm.).
