I have just gotten done with some new signs and thought I would share!This sign I got the plank pre-made at Walmart! I then used the paint pen below for the writing.

This one I just got a plan board and painted it with Rustoleum white paint. 

This board I spray painted with Rustoleum white spray paint. I have to say spray paint almost has a stickier finish so it is harder to write on.

The picture below it the paint pens I used. I got them off of Amazon, but the recently got my favorite ones I like back at Walmart, so as soon as I use these up I will probably be back to those.
