This was sold at a fair, it’s trickier than it looks to get the thin stripes cut, then stuck in a way that doesn’t allow grout to leak under the glass – my top tip would be look at your thin stripe in profile and see if the glass is wavy, if it is, apply at least twice as much glue, or break the stripe where it bends to get two flat bits, much better. I will make more of these, nice for left over bits of glass.
