I enjoy making things, both metalwork and sewing. Being away at grad school, I can't do much metalwork, but I've bought a sewing machine and can still do that. I find it relaxing, I can make what I like and can tailor it to myself (or my wife if I'm making something for her), and it saves money even with buying the pattern if I haven't made my own, fabric, and notions. I don't know how many other men here sew as a hobby, but if you do, please show us!
Here's a couple things I finished recently. This is a pair of trousers from a 1934 pattern I bought from EvaDress.com. I love the syle and they're the most comfortable trousers I own. The pattern includes directions on altering for weight, but I've been working on losing it, so in this instance I decided not to do any alterations. They're a green/brown wool tweed that's greener than in the photos. Button fly, one back pocket, the cuffs are about 22" around and 2" wide.
Xandra was very helpful with a spot I wasn't sure on. We've got a couple more patterns for my wife from EvaDress, but they'll have to wait a few months (well, less than 9 now )
I make a lot of things for my wife as well. She sews as well, but I like making things for her. I posted these in another thread as well. The skirt is from a Simplicity pattern, and the spats I drafted myself. Both are cotton twill with hand-worked corded keyhole buttonholes.
Here's a skirt I made her. There's a jacket as well.
