I am working on a site for a fabric/quilting company and I want to be able to set the variants as different quantities. I know that's not really clear but here is what I mean: my client wants to sell in 1/4 yard increments. So if the customer selects 2 yards, the back end will read that as quantity 8 without the customer seeing it and without the customer setting quantity to 8. I hope this makes sense. Any help would be greatly appreciated! Please let me know if this question is unclear!
