i have been dripping but this sounds good... what you just stuff the material in the cart?
I'm using just regular lipton tea bags. Cut a tea bag and get all the tea out and then cut a strip of it. I use a RN4081 so my carts are really small, you'll just have to try and eyeball how big the strip should be depending on the model you use (you won't need alot of material in the cart, the rolled tea bag should be loose). After I cut the strip I take a paperclip and bend the end out, then roll the strip around the end tightly, put the rolled strip and paper clip in the cart and pull the paper clip out. After you have the strip in the cart, just trim the end so it fits. Good luck
