As Larry stated, you can. I would recommend that you still look into making your own dubbing brushes too. There are nights that I just do not feel like tying but want to do something which involves tying and I will sit down and make up different dubbing brushes. It is fun and you will have them all ready made up which will save you time when you are tying flies with dubbed bodies.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
