I've sourced some very good tools here! If you are planning to make more mosaics in the future, it's worth investing in good quality tools. Safety glasses should be worn whenever there's a possibility that shards of tile or cement dust could get into your eyes. If you’re going to work with glass mosaic it’s well worth getting yourself some Leponitt tile cutters. It will save you both time and tiles. I managed with just the side biters until I discovered these brilliant cutters and once you do, there's no going back!
