I reinforce the corners of the parachutes with clear package tape and use 100% Mercerized Cotton Crochet Thread size 10 for the shroud lines. I also string the lines in a nontwisted pattern (see attached diagram) and tie them through a size 5 Barrel Swivel I found in the fishing supplies at Walmart 12 for $1.36.
I think the new production runs of the pre-assembled Estes parachutes use that shroud line attachment arrangement, too. Also, your MX model design would be a good one in which to use M. Dean Black's exhaust-augmented stabilization method (see: http://www.apogeerockets.com/educat...wsletter379.pdf ).
