A good idea can always be developed. My stitch markers included. I've worked along many designers and fellow makers who have requested a slightly different variation to my normal set up.
For example Fuzzy WhatKnots requested a larger lobster, as her customer base is primarily crocheters. I've had requests for lightbulbs instead of the lobster claws, too, to help the less co-ordinated. Finally if you're using big yarn or BIG needles the fabric loop option means you can still use markers.
If you'd prefer a different closure to your markers- just pop it in your basket!
