I need to make a dozen "moon shapes" (like a crescent shape), about 12" long, for a project for my daughter's room. My idea was to cut out the rough shape on a bandsaw then shape it exactly the way I want it with a sandpaper block or wood file. I was planning to use a 1/4" thick plywood for this part (the master template).

Once I have the "crescent shape" I want, I was going to use that as a template to cut out 12 copies using 3/4" plywood.

Can I do this with a router? My idea was to lay the 1/4" thick master template on top of a piece of 3/4" ply. Then I'd route around it and cut out the shape.

Can this be done on a router and what bit should I use?

Thanks,
Greg
