A few Sundays ago Kerrie D. and I took a workshop in working with resin. It was at Pratt Fine Arts Center here in Seattle and it was taught by Anne Randall ( a very knowledgeable and oh so very excellent instructor). Tin has it's limitations and I have pretty much been a purest in that regard, working only with the metals I can find. Now the resin will allow me to add elements I can't find in tin and will expand the visual impact of my work when it's incorporated.
