This template of a hop flower was made for a mash paddle Instructable
but can be applied to just about anything that needs a decorative cutout or just a mortise, etc. I use Photoshop to make the graphic into a usable template. The same "resizing" I do in Photoshop can be easily done on paper without a computer though. All you need for this project is a router, bushings and bit to fit, clamps, paper, typical glue for paper, MDF or plywood and a couple of wood scraps.
