How to - Product by the Foot/Inches?

I was just wondering if anyone could assist with how to list an item that I want to sell by the Inch or Foot. If the person needs 100 - 12 inch pieces I want to allow them to purchase that...but wanted the customer to be able to customize their length to fit their needs. Any ideas if this can be done with Hika? Have the Business version because I thought I could get that functionality, but I can't seem to see where to do that yet. Total Newb to Hikashop, so I would appreciate any guidance on ideas!

Nevermind! I figured it out!!! If you play long enough you will get it! Figured out that I needed to ad a Characteristic to my item...then "Manage Variants" to add the price by the Inch...much easier than I was first attempting by adding options for each and every inch. Woohoo! Solved
