I then measured 3/8" from one of the long lines and cut the paper along that line. This was to be the edge I would align with the joint of the instrument's top and the tail block. The paper was also cut approximately 3/8" from the other long line. Length-wise, I cut the paper to a length where I could tape it to the face of the block. With an awl, I punched holes in the block at each of the marked holes in the paper.
