I taught myself to crochet as a teenager, but hadn't done it for many years. My sister recently learned how to use a spinning wheel, so I have been "forced" to crochet again with some of the yarns that she's making. I found that there are lots of informative videos on YouTube to show you how to get started and learn the basic stitches. (And you can pause or replay as many times as needed without feeling foolish!) This one in particular was easy to follow and very basic: http://www.youtube.com/watch?v=eqca00LdmAc. Videos were a good way to refresh my memory. I enjoy crochet because it makes me feel "productive" during times when I'm otherwise idle, like watching TV. I've tried on many occassions to learn knitting and I could never get the hang of it.
I'm also a quilter. I love it. I compare it to something like woodworking - I love the feeling of taking raw materials and making them into a functional finished item. I haven't attempted making a bed-sized quilt yet, but I've done lots of small projects and baby quilts. I taught myself how to quilt, but sometimes wish I had taken a class or been able to learn from someone who quilted. I feel like my projects turn out good, but there are probably little tricks/adjustments I don't know about that would make them better. Just knowing how to sew is a good start toward making a quilt.
I find both crochet and quilting to be the type of thing you don't necessarily need a lot of time to do. You don't have to complete a project within any certain timeframe. There are several phases in the quilt-making process, and you can walk away during or after any phase and come back to it later - even weeks later. With a crochet project, I keep the project in a basket on the coffee table and when I pick it up on any given evening, I might only do a few rows, or I might work at it for 2 hours, whatever I feel like.
I encourage you to try any or all of these things, Catherine! I would say of the 3, crochet is probably the easiest to learn and a very low investment. A package of hooks in assorted sizes is less than $10 and a ball/skein of yarn to play with is all you need to get started. If you try it out and don't like it, you haven't wasted a lot of time or money.
