2 Custom Envelope Dies

I am creating 2 custom envelopes for a client's wedding invitation. The steel rule die-maker needs a .pdf showing the black outline for cut (solid) and score lines (dashed). I have scanned in the dimensions of the two envelopes, in their unconverted/flattened state, for "tracing purposes." The finished size of the smaller, response card envelope is ~3.56 x 5.5. The finished size of the larger, square envelope is ~6.56 x 6.56. Any experience in creating die-lines for steel rule envelope dies is valued.
