Again, thanks for all the expert advice. I finally abandoned the straps for now, concentrating on my hammock body. Maybe I should have started there first, as I'm pretty sure it would have saved me a lot of fustration and bad language. I have, after quite a bit of practice on scrap material and having to go real slow, the end seams of a hammock sewn. Finally. Whew! I did find that after I sew one seam on a side, going back over it to double stitch is not a problem at all and goes much quicker. So for now, I'm out of Sam Adams Cherry Wheat, so will get more tomorrow and start on the sides. Funny, the more I drank, the straighter my hems or seam or whatever you call them got. I think it's a rolled hem, but not positive. Then all I have to do it whip it (Whip it real good) and I'm done. I'm hoping it won't take me 4 hours to do 2 seams this time.
I do have to admit, my confidence with the machine is goign up with every seam I sew, so I'm sure I may actually be able to make something that I can actually use in the next decade or so.
