Josebaca,
I read your reply after finishing the last batch, but I am curious about running water over them...what would that do? How would that work...logistically speaking? I could have set up a sprinkler in the area, but since they are about 2/14" tall, I could only run water over one at a time.
Could you elaborate on the process? maybe find a link to a photo of the finished look online? I wanted to put some circle shapes of varying sizes onto some of the units, but it was just too crazy with the pouring process, and I didn't leave myself much of a path to get back to the earlier ones. I DID put rings onto one of them in honor of the wedding anniversary of the couple who loaned me the concrete mixer (good friends). I had envisioned putting different sized circle indents on some...and allowing some of the circles to go off the edges. But I really didn't think ahead to tools to do it with (more circles in varying sizes). I thought of my set of round biscuit cutters, but they would have been pretty small, and I really didn't want to use them for this purpose. I used a couple of the cut sonotube rings for this...
