There is an expanding trend in garden art which looks like it may be here to stay a while. People have discovered they can easily create somewhat pretty pieces of art for their gardens by simply using old recycled glass dishes. Mostly a DIY project in which you can take copper tube and afix glass plates and bowls etc to the end. The copper is simply inserted into the ground giving you some pretty glass flowers for your garden.
In order to successfully recreate these pieces yourself you will need to visit yard sales frequently as well as shop at thrift stores looking for any old dishes and glass you can use for the flowers. When you find something be sure you grab it as it can be a difficult task to find just the right piece of glass which will look perfect in your garden.
