I really want to learn how to do mosaic projects. A friend of a friend made this terrific coffee table (she found a plain old wooden one and refinished it and did a mosaic on the top...) I saw some kits you can buy online at craft stores to do like picture frames or vases, it this a good way to start? Is it super hard? I looked locally for classes and haven't been able to find anything in my area. Does any one have any reccomendations for a first-timer???
