There are a number of home ideas for painting seaglass on jars, but this is the prettiest one I use: http://www.carolynshomework.com/2014/05/etceteras-diy-faux-sea-glass-jars.html
Hi Patricia, Here is a link to the paint which is real easy you just spray it on.
There are just so many ways to paint glass. For a cool effect, you can pour craft paint into the jar, swirl around, then put upside down to dry and for excess to come out.
There is sea glass paint out there also which looks so pretty, especially in the summer.
You can tape around the glass with painters tape, spray with a metallic gold spray paint.
Spray paint, acrylic paint both work great on glass. You can also use chalk paint.
