I think, ladybird, that you first need to narrow down what kind of crafts you would enjoy doing based on your current skills and pleasures, how good you are with your hands, how meticulous, or sloppy you are, do you want quick results or do you enjoy the journey more than the resultand how much time and space you can give to it
T hen think about what interests you.Are you interested in traditional crafts like doing needlework and, say buying a sewing machine, or would you like a craft that is eminently portable and can be done anywhere, even in public without embarrassment, like knitting. Are you interested in being really creative, in which case using textiles and other fabrics to make works of art where you can incorporate all kinds of other crafts in your work may be interesting.
Then there are crafts, which I hope people who do it, will not take it amiss, if I say they are essentially assembly crafts, assembling craft kits for Christmas decorations for example or to decoupage (based on cutting paper) and stamping.
Have a look out for local education courses in the evenings or during the day. These are not outrageously expensive. You might like to test your interest in a craft by doing a one term or weekend course. Google and you will find all kinds of courses, day, weekend and so one. Some expensive, some less so.
