this mold is 12 x 24", so simple to use, place your wood inside, clamp down and add resin. No messy caulking to deal with, no tape and time consuming construction of building a form. This form is well worth the money and reusable. What I like most about this form is the beveled sides for easy release and once project out of the mold, you can run it through your planer easing the number of hours sanding..
