I know I'm asking a lot of questions lately but it's starting to get really warm and I'm remembering all the things on my boat that still drive me crazy!

Number 1 today? No cupholders. None. The boat hasn't had them since I owned it. I love the look of the factory speaker pods + cupholders and was going to try and build some but I won't be able to sew the vinyl and am worried it's going to look strictly ghetto. I was thinking of cutting the triangle(ish) shaped back with the speaker cut-out, then screwing/gluing a perpendicular brace that would hold 2 stainless cupholder inserts and then stretching vinyl and upholstery padding around the whole thing. Would it look super cheesy without any sewn hems? Is there going to be an easier way to get something done?

I experimented with some of those wire basket cupholders a few years back. They didn't last very long and looked TERRIBLE!

Any other simple/easy solutions that look and last?
