Now you get to find out why they make MDF... Buy a
sheet for making a mockup up and if it works, paint
it. If it doesn't, burn it. Mdf is a wonderful cheap
material that keeps a nice edge and allows you to
"see" the possible results without risking your good
wood.

The shelf is 19" wide x 9 deep. I'm new at this so It will be a
practice piece to work on some decoractive touches.
