Granny square beach bag

I have been working on this bag for a couple weeks. My plan was to use it as a tote bag, especially for the beach. It is made out of acrylic yarn so it should dry relatively quickly (if it even soaks up water) and be washable and durable.
I would also use it as a grocery-tote or carry small books in it.
Because of the colors I wouldn't carry it all the time as a purse. I thought I wouldn't want to use it as an everyday bag because of the homespun vibe (I think clothing and accessories can look a little too homespun), but now that it's done I don't feel that way.
Nate and I talk about me selling some of my crochet, and he thinks this could be a big seller. What do you think?
