I don't know if you've tried this or maybe this is what you did. When I cast stamps or something that doesn't take up the whole tube I would take a piece of wood, the same kind of wood that would be on the bottom half of the pen, and make a copy of it on a color copy machine. The only thing I had to guess at was how dark to make the copy because when you finish wood it darkens as well. Sometimes it was hard to match the two. The other was the seam. The darker the better the copy because you can use a pencil or marker to hide the white edge of the seam when you cut the paper to fit. Take the marker and drag the side of the tip along the edge of the paper. There is also the grain matching at the seam but I just put it under the clip and lived with the rest. I've unwrapped a few cigars in the last few weeks and I can tell you the leaf is wrapped like the stripes on an old barber pole. I don't know how old you are they are in a spiral like threads on a screw. Ha Ha. I would try to copy the tobacco leaf and try to get one with a lot of stems through out and darken it up a few notches. Like I mentioned earlier color the edges with a marker and glue it on the tube the same way it was wrapped around the cigar. That way you don't have to worry about straight line seams. The pen above looks great to by the way. Good Luck.
