I just got back from two weeks at our "farm" (really a nature preserve) in the mountains of south-central Pennsylvania. I now have an auxiliary studio there for making backgrounds for larger pieces (mostly 11" x 17") on fiberboard. It's exciting! Sorry I've beem AWOL from the KK, but I'll try to find time to make a piece for this week's theme.
In the meantime, here's a link to a truly ancient collage—from 2010, when I was first making collages on book mailers—with circles on it. I have no idea where in my files this piece is located, so I can't upload it directly.
