what a great opportunity to make them from scratch.
I would learn inkscape (vector graphic program) just because you will learn to make more precise parts with inkscape than easel.
then I would learn to import these files into easel for cutting.
I would get some cheap material (scrap) and practice cutting on that until I became proficient.
man o man to have time off. (I am considered essential so I have no such luck).
P.S. there are some great videos that can show you how to create 3D objects and carve them if you have that much time. here is a video to start with if you have the time. KEVIN! | Inventables
