There are a lot of interesting hobbies on this thread. I think I'll add my own.
Reading is one of my favorite things. I love being engrossed in a novel and being in a new place with new people or learning about new things. It's just a great way to challenge your mind and your perceptions of the world around you.
I love to cook/bake. If it sounds good I will try to make it. I have really been focusing on Italian food lately especially homemade pastas. My lasagna noodles are getting better all the time. I love it because not only do I get to make something nourishing for people I love, but it's a way for me to take care of people. I really like that. A lot of my baking ends up going to work with my husband, and I love to say that I have many fans.
I also love to crochet. Another way to take care of people for me. I haven't made anything for me yet, just afghans, scarves, slippers, and pillowcases for friends, family, and babies on the way. It tickles me when I look down and see that I have made this huge blanket and that someone I love will be kept warm by it. (Sappy, I know)
I cross-stitch at times. I really like taking something blank and watching it slowly come to life with every stitch. It also is a great way to pass the time if you are no where near a computer. Haha.
I'm a music nut. I play it badly, sing it adequately, collect it fervently, and dance to it involuntarily. I adore music. It's the one thing that I can always go to when I need my mood enforced or changed. I love especially to listen to it while my husband plays bass along with it.
Finally, I work in stained glass. I got all new tools for my birthday this year (July 6th) and am starting my first project. I am restoring an old armoire that had stained glass panels in the doors that were atrocious. So, I am making rose panels as replacements and then we will rewire the light inside the doors and refinish the whole armoire. I am so excited about getting it all done. I will definitely post pictures when we are through with it.
A lot of my hobbies allow me to express the caring nuturing side of myself which is more like 75%. I have been like that since I was a little girl and I just don't see myself not wanting to take care of my family and friends any way that I can, even if it is just a hot meal or a crocheted blanket. It's a good thing I like to or these probably wouldn't seem like hobbies.
