Wow... i just did this today for a new project. Cause I'm a big rocketeer now so i don't have any BT20 laying around.
I taped the motors together with scotch tape, then wrapped them from one end to the other with one layer of packing tape. Use white glue on the kraft paper. Glue wont stick to the tape. The packing tape should be just enough thickness that it's not difficult to slide a motor into it.
This is about 6 layers.
