Shari, Thanks for sharing this. I'm always interested in testing different tubing.
Joe, I answered your PM. Sorry, been a busy day, just saw your PM and post.
So, figure out how much is needed to fit around the wheels and then shorten by about an inch. I now don't even sew the pieces together; instead, I insert tubing that is about and 1-1 1/2 inches long inside the ends of the tubing.
To do this I fold that small insert tubing in half (and I don't mean end to end), a rolling of the tubing technique. I also put a drop of sewing machine oil on the ends to help get the insert tubing to slide into the ends of the long tube without too much difficultly. Once the insert tubing is in place, I just slide the ends of the long tubing together. No sewing or stable is needed to hold the long tubing ends together. This all makes for easier and less work if an adjustment needs to be made.
Have fun treadling!!
