My big pieces use a lot of table space and they can't be moved while I work on them. I get antsy to work on something while I wait for them to dry between stages.
Earlier this year I saw a demo by Lori Alcott Fowler and saw how she did some great small scale pieces using metal in the legs. I am exploring the process and trying to make it my own. I allows me to work quickly and move things around while waiting for my large pieces to develop. I am always open to what happens along the way.
