Lap Top Case Pattern

I’m looking for an EASY, no zipper, pattern for making a quilted lap top cover.
So far, there has not been anything to catch my eye on Pinterest.
Well, the ones that do catch my eye seem a bit difficult.
Any suggestions would be appreciated.

I will be trying to make one from a jelly roll, but I do not have a real plan.
