These are very pretty beads, but once again my INCH brain failed to properly visualize 4mm. HELP us INCH folk out on the tiny things and place a bead next to a size reference? I would have ordered a larger size. I've got the round beads down pat but still struggling with the tube and coin beads and getting the right size for my project. I'll absolutely use these, they are very pretty, just not in the project I had planned in my old brain :)
