I have come to love doing my collage and mixed media on wood panels. It gives a nice rigid surface, and has a durable quality. For small panels I like to use Ash wood in a chunky thickness so that the buyer has the option to set them on a shelf.
I am so blessed to have a supportive and handy husband! He goes with me to the lumber yard, advises me on quality as I select my wood, then hauls it home and cuts it to the sizes I want.
Then, he patiently sands each board until it is silky smooth and ready for my use.
These are a favorite for gluing on my Citra Solv creations.
