I have a few old mists still, the kind you have to swirl forever to get it mixed up. Then I purchased some Spritz and they got clogged after the first couple of uses. About a year or so ago I bought some Heidi Swapp color shine but don't really care for it. I basically just wanted it to add splatters to my layouts but found that I can achieve the same look with water color.
I have a drawer full and most of them are clogged. I like the Ranger ones...they put the ball in the bottle to keep it from closging. Fav color--always like the blues but it really depends on my project. Try taking your sprayer out of the bottle and letting the drips from the bottom create the splotches on your paper.
