Fun twisting lines make great knots, and great geometric stained glass patterns. Monochromatic or colorful, this is not a difficult pattern, and the surrounding jewels dont take any time at all to cut or grind. This particular pattern might be better wrapped with a chain as a border than a u-channel zinc. This type of chain is available at your stained glass supply store. If you want this pattern for your child, tell them its a stained glass pattern of strawberry gummy worms--(LOL).
