Can anyone supply me with reasons why this may not work, or suggestions for a different process?
I'm starting with an upholstered rocker. The seat will be replaced with wood and carved rigid foam, then thinset. For the back, I am looking to apply strips of plaster of paris, tacked to wood frame, directly on top of fabric. Then I will apply a few layers of thinset, followed by a mosaic application and grouted. Thoughts?
