Scarlet and I painted glass votives with watercolors yesterday. I remembered this project from Once Wed I saw years ago and it was a very simple and pretty thing to make with my daughter.
I love how she instructed me to not rush and not copy (she saw me sneaking a peek at the original image). The project is very simple, you just paint inside the glass. At times we swirled the brush and sometimes we did straight lines. You can put them upside down or right side up to drip. Layers can also be applied.
