I found that I could easily mount the cards in the jaws of my rotary vise and then spin the vise to wind the material onto the cards. I like the fact that the I could keep a nice uniform tension on the material while it was being wound onto the card to reduce the bulk. This method does not add additional twist to the chenille material like hand winding tends to do. It is a fast and simple way to card materials.
I figured I'd share this in case others would find it useful.
