Here's how to make your favorite hoodie less lethal -- and I did it at TechShop!
So we're going to cut these short, instead.
First, make sure you'll have enough drawstring left when you're done. Stretching the hood out a little bit will pull the strings into it. That's as much drawstring as it'll ever need.
I like a simple overhand-knot, because I can tie it with one hand for the picture. Blam.
Eyeball it so that you'll have enough tubing for both drawstrings, and a bit left over for testing.
So I cut it well-below where I expect it to end. Just leave a bit of drawstring to do a test with.
This looks about right to me.
(WARNING: I did not finish my degree in aglet-making. I dropped out in the last semester of my fourth year, to pursue the circus.)
Slide the tubing over the ends of the drawstrings, and snug them up against the knots.
If a small plastic kudu wanders into frame, ask him to take a picture of you heating up the heat-shrink tubing!
