Sell or dump the hard tinsel. You can wrap some very nice jigs using the plastic mylars that are sold as Christmas tree tinsel. However, for many, you'd have to tie off the collar, just like any collared jig with feathers or fur imho.

Other types of tinsel are sold at craft and fabric stores. You can use a bobbin and finish with these using no thread at all. They are sold on wide spools, so dedicate another bobbin to these. Some are so strong that I can easily whip finish by hand with them.

Hard tinsel is good for ribbing chenille bodies. However, it doesn't conform well to a thinner, thread-wound body. Nor can you whip finish by hand with any ease using them.
