Ben pretty much covered the easy way to go about it, with an excellent write-up.
Now that you have made a few lures, perhaps it is time to draw your own, now that you have a feel for what is required. Personally, I use CAD, only because I am a CAD engineer. Freehand is fine, but look after your originals.
Years ago, I offered to start a lip library, were you could choose from a library of shapes and receive a PDF file of a page of lips for printing. I intended to extend it to lure body templates too, but no one was interested.
