Cooking is definitely in the plan! It's one of the things I miss most about not being at home and it's also kind of a hobby. I recently picked up some supplies for molecular gastronomy so will finally have time to try it out on different recipes (approx $50 of supplies that will hopefully last months). I bought the supplies in bulk as opposed to the kits that companies sell which are significantly marked up.
I also would like to get a little more involved with wordworking, I have the basic tools required but very little practive. I'm thinking that I would like to try making plaques and mount for a few of the antlers I have stashed in the corner of the garage. If I can find some cheap or scrap hardwood I would like to use that for the mount.
I believe my spending will rise a small amount simply because right now my room, utilities and food are covered by work but planning to keep it to a relatively small rise.
