I've had this large, sort of cheesy piece of art hanging above my desk for a while, and I wanted to paint the frame white to have it pop off of the wall color in my bedroom. (Plus I love painting things white) So I took it down, and started to mask the image with blue painters tape - when it suddenly occurred to me that it might pull up the image with it - it did!!
Since I'm bizarrely attached to this print (reminds me of the pond on my grandmothers property) I "framed" it freehand using white paint. I used a water based gloss enamel, and did about 5 coats - I wanted it to be super thick and opaque - like shiny marshmallow!
