Just finished mosaic columns for my Daylesford garden. They are made from glazed and terracotta pots assembled together to form a column. Once they are in their final position I& post some more pictures.
Stacked lids, bottle tops and caps. Fun for kids, but would also make great garden art! I'd think the trick for doing this project is to collect as much different color, shape & size of lid/caps as possible before start putting them together.
