We have over 20 different colors/types of paint in the Inn when you add all the common spaces, 9 guestrooms, baths, and various trim paints. (Remember all those posts on painting? Phew!) Some of the colors are used several times but it makes for a lot of cans and buckets when it comes to do touch ups--which is much more frequently than you might think. It is a constant process keeping up a 200 year old home!
Paula had the idea to make the touch up process a bit easier by filling some baby food jars with a bit of each color. We have a master list of colors and have all our cans and buckets labeled but now all we have to do is grab a small jar and a q-tip which we have found work perfectly for the tiny touch up and BAM, done! Gone is the hassle of prying open the paint cans, accidental spills, and cleaning out of brushes.
It's also a good way to keep a sample of the paint you are using in case you need to go color match it. Do you have any clever ways to do touch ups?
