Much like a paint-by-numbers diamond art tells you where colors are supposed to go on a canvas these pictures can be anthing the artist can think up and can be purchased in kits that include all of the gens and the canvas as well as usually a tray and pen. The gems come in two forms, square and circle and apparently there is intense clans among the hobbiests as to which form of gem is the best. I personally like the circle ones as they seem to get the best shine. I enjoy putting on my podcasts and placing gem by gem down on the canvas until the whole, beautiful picture is revealed. They can then be framed and hung on the walls and they catch the light in lovely ways.
