I was wondering from some of the professional injectors on the site, which injector is the best for putting together a hammock? One that will stand up to the thickness of the material being folded over several times and that will work good with heavy thread. I have a freebie Brother model 1211 which is about 50 years old. It is all metal and seems to be well built, but when trying to sew through webbing with a heavy thread it will not do it. It either locks up and gets stuck in the fabric, or it knots everything up in the bottom.
