This is one of those things you do, just because you want to do it. The results are not spectacular, but the process is enjoyable:
I cut the two images on the outer edges of this bunch from matt black vinyl, and stuck them onto card. Often the negative shapes that are left behind from cutting are quite nice, so I took the negative shapes left over from each to make the cards next to them. The central image is made with whatever was left over shapes from both of the first images.
I’ve been thinking about accountancy lately, and maybe this is a kind of visual version of credits and debits.
