So we have all these old cans of paints that the previous homeowners left in the basement... many of them colors that weren't even on the walls when WE bought the house (Like that yellow, for instance. That pink, unfortunately was. I'll have to post a picture of the pink room sometime. Even the closet door and ceiling and the CEILING FAN BLADES). We've opened the cans up to dry them out to dispose of them.
Then I thought... Hmm... we have all these random boards they left lying around the backyard, what if I used some of these old paints to slather them in bold colors, then painted fun signs to hang from the fence around our pool/yard/garden.
So I did. Paint them bold colors.
