Someone asked me the other day what the most important tool on my workbench was. I laughed and said “my brain” then I said “my hands”. No she said, she meant an actual tool. That took a little bit of thought. I have many different tools, wire cutters, many different types of pliers, curved, flat and round nose, a few pairs with plastic heads, several pair of crimpers, a bead reamer, as well as a few tools that I’m not even sure of the name of. Some I use many times a day, some not as often.
There are lots of great videos available on YouTube that show you how to drill sea glass. When I started drilling sea glass that’s where I got information on how to do it. That, and by doing an online search for “how to drill sea glass” and reading tutorials. But, as I quickly learned, NOTHING teaches you quite like experience.
