You can use can lots of things besides dubbing wax. Anything tacky.
Lip balm would be good. I use bee's wax.
Dubbing loops are good for when you want 'fuzzy' rather than tight dubbing... big difference. For a hair's ear, you want fuzzy
To make a loop, you need a hook with weight. A paper clip bent with just a short hook to go over the thread works fine. Weight the bottom with a large splitshot.
Run a section of thread with your bobbin down where you want the dubbing to begin. Put your new tool inand run the thread back up to where you started and make a couple of wraps to hold it in place. Bring the thread forward.
Then just open the space between the loop legs and evenly and sparsely spread out the dubbing. Spin to twist the loop tight (but not too tight)
Wrap it forward. Rather than make the dubbing too thick to begin with it's better to wrap over it a second time or even a third.
When you have enough, secure the end of the loop with the bobbin thread and cut off the excess.
