we are at stage when you sand after you applied the three coats of epoxy. Is this correct–you sand until the epoxy is grayish-white?
Yes, uniformly dull with no shiny bits. Ideally, you need to stop sanding just before you start cutting into the glass and when all the shiny bits are gone but it’s OK to stop sanding a little bit sooner as long as there are no shiny spots. Usually it is impossible to satisfy both requirements at the same time on the first attempt, not through any fault of yours, just because of the unevenness of the epoxy coat.
The solution is to stop before sanding into the glass (always the higher priority), apply more epoxy to the shiny parts (the areas of thinner coating) and resume sanding when it cures.
For best efficiency, when recoating add epoxy only to the shiny parts. You’ve already sanded the hills down, you don’t want to create new ones which you’ll just have to sand down again.
Once all the shiny bits are gone, with maybe the exception of a very few scattered tiny pinholes, you’re done.

Thank you so much! We are stuck on this part-trying to figure out how it should look and when to stop. At this point, in our long journey, I want to finish this—it does not need to look
wonderful–just want to finish it and start using it with our granddaughter.
Thank you for your help!
Sincerely,
Carolyn
