What are some unique glass and crystal items that retailers can offer their customers?
Card holders, goblets, wine bottles in different sizes, butter and cheese trays, etc. Etching on all of these is all food safe and they can go through the dishwasher. Crystal paperweights of any shape make great gifts. One cool thing you can do is smash thick pieces of glass then grind and polish them. You can make mosaics with the pieces of paperweights. Use several different colors.
