Try and draw it.
Make a grid of squares and slowly draw the shapes using the squares to about keep on track.
Alternatively you could print it off in a larger format then use first tracing paper to get the outlines, then use carbon transfer paper to put the design on a flat bit of board.
You could make the copy onto mdf X amount of times*, cut each one out and make a template of each using a router and template cutter. This way you'll have a series of templates you can use time and again.
* because bandsawing it out its not going to be exact, you go over the line then sand back till exact, then the opposing bear, etc so you have 4 templates
