Textiles. You can get a decent 4 shaft floor loom used for about a grand and a good new spinning wheel for about the same price. Once you get up and running the basic process is a bit time consuming (though not as much as you might think) but pretty simple.
More decorative Textiles can be made even more cheaply but often require more time investment/technique. Bobbin lace only requires bobbins (maybe a buck a pop) plus thread and pins/needles. But I don't think you can make anything wearable.
You can also look online for a local spinner/weavers guild.
