I had a "bad" year when I started several projects and had them going (or NOT going) simultaneously. No matter which one I worked on, I felt frustrated because I wasn't working on the others too. I learned my lesson! Now I have one "major" project for the year that I consider a challenge for some reason (viz. something I hadn't tried, hadn't had much experience with, or with fabrics or a pattern I simply adore). This year it's Jinny Beyer's "Moonglow". I take my time with the annual "major" project and enjoy the process and the learning experience. In addition, I do quick projects like small wall hangings, table runners, pillows, totes etc. (again, one going at a time as the mood strikes me). This approach allows me to enjoy my other hobbies without feeling "overwhelmed" or pressured by WIPs or UFOs.
