This mounting option is rock solid and produces nice stable video, but at the expense of comfort. It's perfect for strapping around a solid fixed object, like a ski boot. You can strap it around a hand, arm, leg, chest, etc., but it won't be as comfortable as using the elastic since you need to make it as tight as possible to produce stable video.
I used 1.5" width flat nylon webbing, 1.5" buckle, 1.5" slider, and the goggle mount as the base. You should be able to get all the materials locally at REI or EMS.
1) Measure out a length of nylon webbing that is 2x the minimal circumference + 2" or 3" for the overlap and sew area of the target object this strap will be attached to.
2) Grab a lighter or a match and melt the ends of the nylon webbing to prevent it from fraying.
3) Sew the female end of the buckle to one end of the nylon webbing. If you are sewing with a machine make sure your needle and thread are capable of working with 2x the thickness of the nylon webbing, you don't want broken needles flying around ;)
4) Thread the nylon webbing through the slider and the male end of the buckle, then back through the slider, overlap the end and sew. Look at the next picture for visual explanation.
5) Attach goggle mount. Depending on thickness of your nylon webbing, attaching to the side of the slider that has two nylon webbings versus one should be enough to make the camera nice and stable when attached to the goggle mount. If you attach the goggle mount with only using the single nylon webbing you will probably need to add a filling material between the goggle mount and camera mount to prevent the camera from wobbling in the mount.
6) Strap it on and adjust fit to make it as tight as humanly possible without breaking anything or cutting off circulation if you are strapping it around your body parts. The tighter the strap, the more stable the video will be.
