Startup Idea: Yarn Inventory Management and Archive Software

Startup idea to develop a software that allows yarn shop owners, especially Etsy sellers, to manage their inventory by listing all colors, weights, styles and brands of yarn. The software should also have a search function and pattern archiving feature. The idea aims to simplify inventory management and reduce time spent on verifying stock.

I am looking for a software that I could import all colors/weights/styles/brands of my yarn (I own an etsy shop and have a huge amount of yarn for projects) and could easily search through what I had for what I needed (better even if I could look while I was at the store). I spend a lot of time thinking "do I have this color?" and yes, sometimes I do, but it's the wrong weight.

Even better would be if I could archive patterns as well and easily pull up the yarn specs (ie; how much and of what color I need). I have a bit of a "system" for organizing but with the amount I have it can get overwhelming. Thanks!
