Today I sucked it up and attempted to make something involving a zipper. It's not perfect, but you won't see the zipper until future baby pukes on this side a few times. Even then, I think the zipper should at least be out of the way of baby annoyance zone. The zipper even works...so far.
It looks like there is lots of loose fabric, but when I tried it out, it seems like that fabric spreads out once the pillow is in use around my big tummy.
Anyway, I loved the fabric, and I'm fairly pleased with how the cover turned out. We'll see how it holds up to actual use.
