I'm always looking for how to decorate and redecorate every room of my house; and now it was the turn of the playroom. Looking for ideas I found this in a little of this. a little of that. I did basically the same thing that she, but with a few small changes in materials.
Instead of vinyl I bought at Hobby Lobby wooden letters. The wood at Home Depot and clamps at Target ( in the section of $1)
My dear spouse cut wood, that was initially of 10 pies, by half. Then I used white paint that had previous projects. To paste clips only I used my 'glue gun'. My Woods are glued to the wall with screws (I am so sure that you were not going to fall into the head to my daughters) and ready! Now where I have put my daughters masterpieces.
