A clutch or purse organizer
May be nice with a blue green cake for a water look
The single rib crochet stitch is super simple to do. If you can double crochet and chain you're in business to whip up some awesome crochet texture!,,, it's basically a front post double crochet.
interesting - If this could be worked up using plarn (plastic bag "yarn") it might make a nice swim tote.
