Use small Neodymium disc magnets instead of snaps, velcro or hooks
Sometimes I sew very small doll clothing-one of the small dolls I sew for is only 4" tall. Sewing snaps is a pain at best, hooks and eyes are too cumbersome, and Velcro can be a mess. I found that I can easily glue VERY SMALL neodymium disc magnets to her clothing without a lot of hassle. I use E6000 glue-a VERY tiny dab works, and is permanent.
