Sewing with a sewing machine is fairly easy.
If you don't know how, poke around at the local community college and see if they have any courses, check with libraries, or ask at a sewing/craft store about classes.
If none of those are an option, see if you can get a friend/relative who knows how to teach you a bit, or get an intro book out of the library and just practice and teach yourself.
Something like a filter sock should be really easy, and you may be able to figure out how after playing with some scraps and stuff
