Too many variations. I need help!

Hello,
I have a website that sell fabric. users can select an artwork from our library then select the fabric(30 choices/variations) they want that artwork printed on. That’s the first issue. The second problem is that, from time to time, we can run out of some fabric in our store. When that happens, I need to be able to easily disable that attribute/variation temporarily until it’s back in stock.

Is there a plug-in that can help me solve this issue? I’m using woocommerce plugin

P.S. I’m not a web developer. I’m a total newbie when it comes to this.
