One Response to “Building Your Own Sanding Blocks”


    Great idea with the Yoga blocks. One thing to mention is a flat surface on the block. The commercial Dura blocks are not always flat on the bottom and it will change with use. I use a flat piece of laminated glass and stick a length of sandpaper to it and sand my blocks. Any good known flat surface will work. my buddy uses a piece of 1/4 inch aluminum plate. It is amazing to see how imperfect your blocks are when you start to sand them. Check your flat surface with a straight edge.
