Spirit Board Update

IN PROGRESS: Still painting away on my piece for the Spirit Board group show. I'm just a few days away from completion I think! The main elements are here, minus one very special detail that will be painted in a bit later, and I'll post that final photo here when possible. This unfinished painting measures 26" x 36". Building my own canvases gives me the flexibility to build the appropriate shape for the idea, and I love canvas. For the sake of durability though, I'm having to consider moving to board eventually, especially since I like to work large. Transporting canvas is always nerve-wracking...but I am not such a fan of that flat texture. I found a company that makes custom sizes, only problem is they sell their boards raw...so's there's not only no ground on which to paint (and I've had unhappy experiences applying my own gesso to wood), but there's no sealant to protect the paint from wood acids. I'm shocked at how many artists paint oil directly on wood and then marvel at how that wood just soaks in all the paint. That is a process that will devour a painting over time. Wood acids mixed with oil, no ground to hold them in...strange to put all that work into something so unstable. Even canvas expands and contracts over time, risking cracking. Such is the nature of ever-changing organic matter!
