It will take some practise to get it down pat but if you copy what I have shown you in the video you will make a useable filter in no time. FYI I “accordioned” the filter 5 times in the beginning before I rolled it and I’ve found that the best filter length to be the width of the business card. It doesn’t need to be perfect, it just needs smoke to pass through it. Good luck
