Studio Re-Do #3

OK, so I have had many things going on and the studio is advancing at a snail's pace.  However, I managed a quick fix in very short time this morning that I want to share with you.  I have seen several photos on Pinterest that show off some clever use of homemade chalkboard paint.  Some are chalkboard walls, old silver trays, and some are just painted boards in a  frame.  I chose the latter for my project.  I had a nice gilded frame sitting around waiting for a picture to beautify, but no board to fit.  Taking myself off to the craft store, I found that the canvas boards were sold in packs and would cost me far more than necessary.  So, I grabbed up a white foam board for this project.  Now is where I get experimental.

All the Pins I was used un-sanded grout mixed with regular latex paint.  I had checked with the local Lowe's, and saw that a small bag of grout was about $13.  Not bad, but all the recipe called for was about a teaspoon of grout, and that just seemed ridiculous to me.  So, after a friend suggested that joint compound would probably work too, I mentioned I only had the already been mixed kind.  "No matter" said my friend, and I am glad I listened.  I had this big tub, and some deeply purple paint to play with.  I mixed about 1/2 cup paint with a generous amount of joint compound (perhaps 3 Tablespoons, I did not measure), and spread it on lightly with a small trim roller (though just about any way of application would do).  I smoothed it out afterwards with a very light brushing over the surface.  It dried very quickly, without much warping of the foam board.  I gave it another coat after an hour or so. 

 This is the result...
