Rubber Paint Brushes
These are rubber paint brushes and I LOVE them. I use them for faux stained glass with the liquid leading as well as the paint colors....AND I use them when I am claying. They are so versatile and just work so fantastically. The set usually runs about $21 and worth every single penny. When I use them for the faux stained glass the tips clean up super easily... and although I have had mine for several years and seem to use them on a weekly basis they are still in tip top shape.
These paint brushes are sold as Kids Paint Set. Go to http://www.dickblick.com and do a search under Colour Shaper (Make sure you put the U in color for this search)
