Our living room has vaulted ceilings. There were HUGE holes in the walls when we moved in. They used serious bolts to hang their pictures. Rather than rent scaffolding or struggle on a latter, I wanted to match the paint color and just touch up the holes.
This is not an easy thing to do! First I tried one sample of paint off a spot that was falling off anyway. The color turned out too dark. So, I found a spot that was a slightly lighter color of paint than the rest of the room. I think they had touched something up there. I had my husband take that sample into Home Depot and it matched perfectly! I was so excited. This saved me so much time and money!
