Items needed:
Two spools of nylon straps that are 1 inch wide by 10 yards long, in colors of your choice.
Tape measure
12 inch ruler
Stapler
Needle & thread or sewing machine
First I cut two strips that are 12 feet long.
Then I cut smaller strips (rungs) out of a different color that are 14 inches long. Use a lighter to melt all cut ends so the strap doesn't fray along the edges. To do this you run the end of the strap quickly through the flame until the ends are melted enough to hold together. Be sure to do it in a ventilated area and don't inhale the fumes.
Then I laid the rungs on the two long strips so they overlap to the outer edges of the strips.
I got out a 12 inch ruler and measured the straps so each rung was 12 inches apart.
As I measured them with the ruler, I stapled the rungs in place to be sewn later. Here it is, my homemade speed ladder...
Here is a YouTube video I found with some good speed ladder drills,
