    so Tom posted about bowlines for shock cords.

    Is there a preferred knot for tying shroud lines to low power plastic chutes?

    I just usually push them through the ring of a snap swivel, then pass the parachute through the loops. Easy and the swivel will help with the chute stability.

    I think Babar is asking about the knot that ties the shroud line to the parachute corner.

    Oh, my bad. A bowline would be good there as you would have a loop at the attachment point?

    A bowline sounds like a good idea, but I haven't used them because they 1) take up a good deal of line which is in short supply with most LP kits' chutes and 2) are hard to keep even with regard to the line used, and to thus keep the shroud lines of even length. I just use square knots, but I'm sure there's something better.

    Tom, with regard to the swivel, what you've got there is a lark's head knot.

    Yes it would be very difficult to get the shrouds even doing bowlines I agree. I just like the fact that it would leave open loops at the point of attachment. A double overhand knot would scrunch down into the plastic.

    So I don't know what other alternatives could be considered.

    "Larks Head" huh, been using that knot on a hundred different things all these years and never knew it had a name :)

    Yeah, it does. The thing is, wven with a loop the thread will bite in to the edges of the holes. My way is worse, neither is great, I think.

    Thise paper reinforcers ought to help, but they don't stay in place on the polyethylene sheet.

    I just make a loop in the end of the shroud line (no knot), and use a small square of packing tape to tape it to the parachute. The tape spreads out the load, and it seems to be plenty strong enough for LPR.

    I use a simplified figure 8 follow through knot.

    The simplified version is to use a simple knot instead of the figure eight, over and through. Not, over, around and through. Clear as mud right?

    I just tie a loop with a simple square knot and have never had one come loose.

    Of course, I'm knot-ignorant and use square knots for everything, but in this case it seems to work fine, at least with the carpet thread (?) that typically comes with LPR plastic chutes. I might put a drop of white or yellow glue on the knows to set them when finished.

    The fact that if works fine is all that matters!
