Many years ago, way back when I was a solo act, I found it necessary to cut a hole in the wall in the bedroom/office area to access some coaxial cable. I cut a rectangle out of the drywall, accessed the cable and then put the rectangle of drywall back in place with green masking tape.
This wasn't particularly obvious to the other resident who came to live here because I had a dresser, a bunch of empty boxes, a clothes tree, and a sort of nightstand thing in front of this wall. But I've been downsizing a bit and moving things into my new studio space and the taped rectangle became entirely obvious.
It was gently suggested that I replace the taped-up rectangle with an access panel. I had to agree that this was a very good idea, so I got an access panel, removed the taped-up rectangle, and enlarged the hole so the access panel would properly fit.
Alas, in doing so, removal of the tape that had been on the wall for at least 20 years caused a section of paint to also come off, and I put a longer mark on the wall than I had needed.
Some people would probably have addressed these unsightly blemishes with some sort of paint solution. But I do not know much about house paint and am not good at using it.
However, I can draw a squid tentacle with a Rotring Tikky Graphic C.7 and a set of coloured pencils on a piece of fine tooth surface sketch paper and then use an exacto knife to cut out that tentacle so it perfectly covers unsightly blemishes on a wall.
And that is what I did.
If the other resident of your home has an affection for cephalopods, this is a home repair solution that I can recommend.
