J Ring Glass is located between Minneapolis and Saint Paul in Minnesota. The store has an extensive (several hundred different colors of stained, mosaic, glass rods, beads, system 90 and system 96. He has most of the extras to go with it. I love the scrap bins as it allow new fusers to get lots of little bits of color at a cheap rate. They just added Hot Mix glass which is very cheap. I have taken one class at their store on how to cut glass. It was a great class and I learned a lot of little tricks. The employees are mostly helpful but get short when they are busy working on something else.
