Spraying but no flooding
Bulb sprinkler (or spray brauser) is a great spraying tool for feltmakers. It looks like a bulb syringe for baby’s nose and it is exactly how it works.
During wet felting process you have to spray wool fibers with warm water or soap solution, but you definetely do not want to flood neighbours living below you or to destroy the floor in your house.
This is why I use this bulb sprinkler all the time. Its metal head with strainer allows me to spray water onto my works in a controlled way.
