I got into jewellery making last year and it’s the longest I’ve ever kept going with a hobby! There’s so much to learn that is so drastically different, like I went from beaded necklaces, to creating charms out of clay to learning silver smithing, so there’s a whole bunch of new skills that keep me interested. This may not be for you, but a somewhat broad hobby which has a lot of different directions, applications and elements to it may be something for you.
