Occasionally I get a request for a chalk board sign. As long as the message on the sign is permanent, many times it makes more sense to make it out of foam core board than buy an actual chalk board. It's not always easy to locate an actual chalk board in the size that you need. Not to mention the cost. Lots of these faux signs could be made for the price of one real chalk board. This type of sign would be ideal for a business that wants to create signs with a "market" or "rustic" feel. Let's run through the steps of how to make one of these.
I applied the color in long, uninterrupted passes along the entire length of the strip. Each pass should overlap the last pass slightly. In the picture above you can see that I made two passes. The darker strip in the middle shows where the two passes overlapped.
