I bought some Tyvec to use as footprints for my two Kelty Grand Mesa 2 tents. May sound a little strange. But I wanted to sew some "boarders" around the edges (I guess in hopes of keeping it from tearing and to make it look neater). Also, I may want to sew some angles and different things to fool around with some tarp making. Anyone every tried sewing Tyvec (Sowing Maching)...Any advice?
