Although this isn't a mosaic I thought that I would share it too. I buy many of the glass beads for my mosaic work in large mixed lots and since I only use glass beads in my mosic work I end up with TONS of plastic beads. Some are put to good use by my granddaughers when they come to visit but I was looking for a good way to use them up so here it is. This isn't my own idea - saw one similar on a garden tour this Spring. I call mine a garden squiggle because I can't seem to leave the wire straight!
This close up should give you a better idea of what it looks like. The stake is a hollow piece of copper tubing about 4 feet tall. I bought 16 guage steel wire and strung plastic beads on the pieces of wire. The ends of the wire are inserted in the copper tubing and then I just coiled the wires to make them look more interesting. My photos are not too good - this really sparkles in the sun. It is a fun way to use up non mosaic supplies. They would also be pretty made with glass beads and would probably hold up longer in our brutal Texas weather!
