Fletch, JoC, Ai — Thanks so much for your encouragement and understanding
More comments soon.
TL;DR...
Fletch, as for technique, as near as I can remember, this is probably how I did it. However, different approaches could have yielded the same result, so not entirely sure what I did LOL...
..... Painted a semblance of the background first, testing various existing ProCreate brushes. Made two separate layers/colors because of the sgraffito experiment that I was goofing around with.
..... Then, on a separate layer above the backgrounds, sketched the patterned cat freehand with a ProCreate pencil using vibrant colors to see the sketch against the backgrounds.
..... Next, made selections using my ProCreate pencil sketch as a guide, combining (add, remove, invert as needed) little selections to end up with a single, final selection.
..... Saved the selection.
..... Then, made sure that my top background layer was selected, and loaded my saved selection.
..... Feathered the selection, especially important because the blanket is soft, and woven. I didn't want the cat to look like it was laser cut from paper.
..... Then in the context menu for the layer, selected "Clear".
..... "Clear" eliminated the selected areas in the top layer of my painted background, while leaving the bottom layer of the background untouched.
As I read this, I don't think this is quite what I did, but it will have to do. I kind of got in a zone, didn't save every step, although I meant to. And I always just kind of wing it when I draw or paint.
I took photos this morning of the actual blanket. First, is the square I sketched. Second is the whole blanket with a couple of leaves added for "my" cat to play with LOL
I saved the leaves. If they don't get broken in my mobile studio, maybe I'll sketch one
