Idea for air layering product

Hello! I am a student working on an assignment, and I would appreciate it if you guys could provide me with some feedback on my idea!
I was tasked to use waste materials to create a product to speed up the process of air layering. I was told that string is usually used to tie two ends of a plastic sheet to the stem of a plant, and that the process of tying the string was very time-consuming.

My idea is to cut out a square piece of waste cloth, and attach drawstrings to both ends. This piece of cloth could be used to replace the plastic sheet. The drawstrings already attached to the cloth make the process of tying knots much faster. I have made a prototype, and the cloth is secured quite tightly to the stem and would not fall off easily.

What do you guys think of my idea? Also, if this product was sold on the market, would you be interested to buy it?
Thank you very much for your feedback!
