We end up with all these scraps of Hair-on cowhide from our Upholstery Shop. We have seen table runners and rugs made from these scraps zig-zaged together. Sooooo, what would be a good (affordable) zig-zag machine to buy for this job. We would be sewing through no more than 2 layers of 5/6 oz. hair-on cowhide. Probably 69 or 92 thread...??? Any ideas or thoughts ???  Thanks---------Bill
