I picked up some wire twisting pliers - harbor freight has some inexpensive ones. They have been good for tasks like guy wires or putting wire into a new pot.
I took some saran wrap, cut it in 2 inch sections and it works just like grafting tape. 10/10. Use a bench vise to hold the roll and then cut it with a small tooth saw, a hacksaw(metal) worked best for me. If it gets too hot, it will melt and fuse the plastic then mess up your roll, so go slow. I also tried with a large knife and a razor blade and while that worked, it was fairly dangerous so I would recommend a saw. And now I am using grafting tape for everything.
