I was in Santa Monica last week and the low tide allowed me to explore under the pier. The tide was low but preparing to rise again so more than once I had to dash uphill to keep from getting soaked. Most of the times I made it. Most!! Paul
We have a lot of people where I live that make things like that. My wife has even made a couple of pieces for our granddaughters. Bring the glass along when you visit and you can collect ideas.
While I was wandering around under the pier I found a small piece of sea glass and my hope is to make a necklaces out of it for my granddaughter when she gets old enough to start wearing jewelry. I've got plenty of time to think about how I might achieve that task since she's only 2 and change at the moment. Google and YouTube here I come. Paul
