While cleaning out my garage I came across a leftover roll of landscape material. I decided to try to use it as parachute material for larger rockets. I seems to work very well. Air goes through it and lessens the swaying one gets with plastic parachutes. Just cut the material to shape, reinforce both sides where you mount your shroud lines (I use clear packing tape) Use a paper punch to punch through the material and attach the shroud lines of your choice.(I use plain old kite string)
Try it.

Try it.
