After I had bought them I pondered what to do with the chutes

Tried many ideas nothing really worked .Then I was doing laundry and it hit me STARCH! Yup you got it,good old spray starch from the laundry.
What I did was find a balloon and put some tape on it with a string out through the hole in the top of canopy wrapped the figure in a plastic bag to protect him from over spray. Then hung blew up the balloon till yo have the shape you want the canopy to be in(I went through a few balloon sizes till I found the right one for the look I wanted.) I also had to add a little weight to the figure in the plastic bag to get the"drape" I wanted.
Now begin spraying Don't go hog wild with the spray better to do a few light coats then one drench er of a coat.Let it dry between coats and i would recommend the heavy duty starch. Then let it dry thoroughly and the you let the air out SLOWLY *don't ask how I know that
