Here's Bob's suggestion:
Stem the filler. You can leave the two halves of each leaf attached by 3 or 4 inches of central vein. Grab a leaf or two or three (depending on how fat a cigar you want), all aligned at the end you grab, and compress it firmly in one hand. Using your other hand, tear off all the leaves to the length of cigar you intend. Align the torn-off leaf to the top of the original leaves. Repeat, until all the leaf is used up. Even it out, it you want. With filler in low case, and rolling any cigar other than a thin, Lancero, I have found that I cannot compress it too much. I compress it all firmly, and roll the cigar in its binder.
For me, 3 large filler leaves will roll a 50-60 gauge, 6" honker. It's worth noting that it's easier to get the draw right on a fat cigar than on a thin one. {Bernoulli's equation)
