Filter on roll up cigarette?

Question:I roll my own cigarettes using Golden Virginia Tobacco and Rizla Green papers. I can only seem to find swan slimline filter tips. The problem is that when I roll it and put the filter in, there are big gaps at the bottom where the filter is, so it doesnt seem to fit as well into the paper. How do you get the filter to stay in the roll up tightly like a manufactured cigarette?

Answers:
Try a rolling machine with the right filter tips
