Amazing that we are already at Day 21 of the 30 in 30 Challenge! Today's post is another 5" x 5" piece done on a birch block covered with Watercolor Ground. Watercolor Ground enables me to use my favorite medium but use an alternate support. And the bonus, no glass is needed! It sits nicely on my bookshelf or easel. I personally like the finished look of the wood edges. The question is do I stain the wood or leave the natural birch color?
