Cool ...Easy Way to Stretch Watercolor Paper...and for  Repeated Use!

Read below photos for more information. Enjoy.

This is an inexpensive and easy way to stretch watercolor paper that can be used again and again .  You can build them any size that you will find in a canvas panel and foam core.  It is light , very sturdy and a fraction of the cost of the boards marketed for the same function and I also expect it will last longer.  I have had no warping.  Although my demonstration didn't show it, you could apply a coat of white acrylic or gray house paint to the panel before you put it together to improve life of the panel but I have had no problems.  I hope if you try this, you will be as pleased as I have been.  This is the only system I use now for stretching watercolor paper!!  The foam core on the back side functions as a layer to prevent the tips of the staples from getting through to snag or scratch the painter.:)
