I have an Etsy shop on the side and we sell sandblasted pint glasses. We tried the cream etching stuff and found out the first try that it doesn't work well at all. Now we use a sandblaster. If you decide to go that route, let me know if you have any questions. I sent the OP a PM offering to make them but the shipping alone would probably make the cost too high to resell at what her customer may want to pay for bar glasses.
