Thank you Bev, I have it filled with just sedum now. It is simply planted but its hardy and looked great when it was in bloom.
Carol, I did not have a good table spot for making these either. So what I did is I took four pallets and stood three on their sides and balanced one on top and wired them all together. I am sure if I had wood working skills I could have figured something better out. It worked though and the extra splatters of concrete fall under them to be easily cleaned up later. I also spread out trash bags on the work space depending on what form I am doing. I set this up in area that most people will never see when they come over. I can leave the area as a work space and not have to worry about meticulously cleaning it up between projects.
Trash bags can be used several times depending on the quality. The new more landfill friendly kind of shopping bags only last one time and will be brittle after one use. Also, it is useful to drill your holes for drainage while your doing your first cure time. Sometimes they will make tiny cracks when you do them when completely hard. Any of those tiny cracks can be repaired with second coats. Hope that helps.
