Pattern for hot water bottle cover?

Hi again! I was saying to DH last night that I’d like to knit a hot water bottle cover. The problem is, I can’t find a decent simple (non fancy) pattern for it. Does anyone happen to know of one? I’ve done a google search but only come up with a bunch of over the top, super fancy, overdone patterns. LOL TIA
Et voila. Simply eliminate all the adornments and you have yourself a plain pattern. I’m sure it can be adapted for a hot water bottle.
That one has a cable, but I’m sure that you could get rid of the cable if you wanted and have it be plainer or dress it up however you like.

oh cool! Thanks!!
