My friend, I did the same for quite awhile, as my hands just werent steady enough to roll. I wouldnt recomend using a "filter," as in a filter from a cigarette, as the thc molecules kindof adhere to solids(thats why after prolonged use bowls are covered in black tar like substances), so use a hand rolled roach, which is use cards for. Being a magician who likes to experiment with cards, I have a lot of cards that are wrecked. So, tear of a five milimetre strip from the side of a card(long side), make 6-10 small 3-5mm folds and roll the rest around it. That may be hard to follow, but if you really cant understand it, look up "rolling a roach." Anyways, I hope I could help(though I probably didnt) and enjoy your doobie!:rastasmoke:
