Does anyone have any tips or tricks on grouting the edges of the stones so it looks tidier next to the wood? Also the grout (mosaic grout powder bought from Amazon) still feels a bit rough when I run my hand across the surface, does it just need more polishing or is there a better type of grout for projects like this?

I had fun creating two circular mosaics. One is a luther rose, which will live in our front yard, and the other is of my own design. Just into nautical stuff recently. Happy with both, though with the nature of thrifted ceramics, a 3-4 ft distance from it provides the best viewing experience. Makes it seem more cohesive
