Hi! I have come here before though am not a regular on the forum. I was hoping that I could have some opinions on what I can use for adhesive for beach pebbles? I gather TONS of rocks and pebbles from the beach, and I would like to make a flower pot bird bath using them. Has anyone else tried using pebbles? I literally have thousands...YES, I hoard.:) But I have a thing for rocks, they are used all over my yard in gardens and for lanscaping. Any advice and suggestions would be great! Thanks!
