Reusable Water Balloon Addi Express Tutorial

This is how I make reusable water balloons on my Addi 22 pin knitting machine.

I tried making a few of these using the Bernat Blanket yarn but found it to be too hard on my machine. I saw a few different polyester yarns that I thought would work out for reusable water balloons and found that these other yarns worked great.

Materials:
22 Pin Knitting Machine (I have a Addi Express Professional)
5mm Crochet Hook (H8)
100% Polyester Worsted Weight Yarn, Yarns Used
Bernat Bundle Up
Loops & Threads Baby Rainbow
Darning Needle

Tension: Tight
If using a Savlabot Tension Fork I did the Tightest Tension which is both the hole closest to the machine and the middle hole.
Cast on as you normally would and Crank out 43 Rounds.
Cast off using waste yarn (About 10 rounds or so is what I do) and remove from machine.
Now for sewing it together, I am not sure how to explain this in writing so you will need to view the tutorial for finishing the water balloon.
