would be the easiest. I have a concrete birdbath. It is functional but ugly. I was hoping one day to use those bottles to do the inside of the bowl first and see how that goes. I was even thinking about putting some decorative stones in for them to stand on and to break up the mosaic. I am not nearly as good at this stuff than I used to be or I think I am, lol.
Pottery and concrete figures. Me too. I have a concrete floor in 2 places in my house that were stained and I love them. If I had had enough money (not even close) my house would have been made of concrete and steel. I have one exposed steel beam on my front porch and one in my living room that goes with the factory steel/wood staircase. I really wanted polished concrete floors. Now that they are starting to do injection wells about 60 miles away from me I should be glad I did not. We have had enough shakes from Oklahoma, I am in NE Kansas, so I am guessing we are going to lose some stuff with bigger shakes. Oh how I hate this....off topic.
I would be interested if you did a project if you let us know how it went. I have too many animals out here to take care of, my time for those kinds of projects is short and I am getting too old to find more energy!!
