There are a number of places to buy stained glass – let’s look at a few of them.

The easiest and least risky way to buy glass is in a kit.  You can purchase kits online:  simply search for “stained glass kits” and you’ll see dozens of online suppliers.  Or you can buy kits at Michael’s Arts and Crafts, Ben Franklin, or your local craft store.  Many smaller craft stores may not stock kits, but they will be glad to order what you want.
