I am working on painting a set of glass Christmas ornaments, which is a little out of my comfort zone. I have painted some in the past, but not with a design that needs to be symmetrical. I received a lot of good tips from one of my online painting group members - Tole Friends.
One suggestion was to use pieces of a measuring tape, or a flexible ruler to measure & line up elements on the surface. Since one of my girls borrowed & did not return my tape measure ( and deciding to make do instead of hunting for it!)
I had to stop painting & share with everyone!! If your grocery store does not use this tape - don't despair yet! I have seen rolls of it in my local CVS store in the hardware/household items section. Back to painting!
