Tracing an image

I’ve been helping my wife with her cookie making business by designing (on Sketchup) and then 3D printing cookie cutters for her. She draws the image and then I import the image and manually trace it to create the .skp file which I then covert to an .stl.

I’m just wondering, is there an extension that will trace these images for me? It’s basically a line drawing. I don’t mind (and actually enjoy) tracing them and then extruding them the way I need. But…if there is an easier way, I’m open to it. I’ve looked at Bitmap Mesh, but I’m not sure that fits the bill. Any suggestions?

or with Jim’s plugin

and with Inkscape
