Staedtler makes multicolor leads. They're expensive. I use June Gold leads. Like I said, these are 2mm art leads. But they can be sharpened to a fine point. Depending on what you're transferring or outlining, you might need a finer point. I use these for sketching the designs.
I think I need to clarify...
I use the chacopy to simply place the design. Once cut out, before inlayng, each piece will still have to be placed and traced.
They'll need to be tweaked and I'll use either the Staedtler with yellow lead, or my plain old Zebra .5mm pencil, to trace around each piece, like John Hall taught me. If my hand shakes or jerks while tracing the piece, I can start again. But at least the main design is there, so I know where to put each piece to do the final tracing. Of course, if I'm doing a direct resin pour, I rout the design as placed on the board with the Chacopy paper.
But at this point, my hands aren't steady enough to control all pieces of a larger design like this and I dont like gluing them to the board. Plus, I can see the fretboard through the design on the transfer paper to get the whole thing properly placed. Individual elements can be tweaked as needed later.
I hope I'm making some sense.
