Anyway, fast forward 5 months, to a recent thrift store trip, where I perused the frames/pictures section, and found this great wood frame, larger size, and with a mat. This was going to be perfect for my print! $7.99... sold.
I'm sure I frightened Z with the framed art in the garage for the last week. He should know me better than that by now though! Revamp here I come!
I took the green mat, and painted it with white spray primer (I wanted to keep the texture of the mat, and didn't want it shiny...) This turned out well, considering I wasn't sure if you could even do that! I picked "tool grey" spray enamel and painted the wood frame. I added a hook on the back, cleaned up the glass, and installed. I love this modern look! I may even try to paint a wall with that great green color in the print.
