Super cheap and super easy to do yourself. Just get a small D ring from a craft store or a hardware store. fold over a small strip of material or even a piece of elastic and sew to garmet. Whoops I forgot... you first slide it through the D ring then sew it to garment. VERY easy to do if you can thread a needle and sew a few regular stitches. Like 25 cents to do. Hardware stores you can usually buy 1 D ring or a PACKAGE OF THEM. A D ring is just that a little ring in the shape of a D.
This isn't really good for sweaters but works great for coats and vests and stuff. Sweaters you can just do a button hole to slide the leash through. If you can't do a button hole the chances are SOMEBODY you know has a machine and can do it for you easy.
HEY WAIT , I was thinking... You could probably even do a grommett(spelling) type thing for sweaters. You can buy a little machine in places like AC Moore or Micheals that puches down and inserts grommets. Then you could slide the leash through and no unraveling. Maybe this would work and you can get the home machines pretty cheap to use over and over. AC Moore offers coupons EVERY Week for 40% off a single purchase . Micheal's will accept these coupons
