Step 7: Paint the stones...
doily of choice on top of the stone and give it a good coating of spray paint.
Be sure to focus on the tiny holes, but don't hold the paint too close, or there
will be blobs seeping underneath. A light mist around the edge, then the center,
then back around again, giving good coverage, but not too heavy.
Allow the paint to dry a bit, then carefully lift the doily out of the way, draping it
over something to allow any residual paint to dry on the doily.
Paint each stone, being careful not to step on them until they are completely dry.
