Hardtop Vertical Storage Cover

Hey guys,

I built a wooden hardtop storage cart like this:



Problem is, the top is too tall to fit anywhere indoors, so it has to live outside. I don't get a lot of rain, but there has been a lot of small showers lately. I threw a tarp on it that lasted a month or so until some violent wind ripped it wide open.

Anyone have any ideas or recommendations on how to cover the top outside? I saw that Bestop has some covers, but they don't make them for TJ's and they cost $200+ . I've tried finding bbq covers, patio furnature covers, anything short of fabric that I'd have to sew (which I could figure out if need be).

I wouldn't normally bother, but my Smittybilt top has a nice headliner in it that I'd rather not get soaking wet once a week for a couple months. I'll definitely update if I find something that works.
