To make this great toy for your dog I used, 12 strings t-shirt yarn from about 1,2 yard long.
How to make t-shirt yarn from an old shirt is well explained in this You Tube video
You devide the string in four parts from 3 strings and start the scoubidou technic, one I did with the round technic
and one with the straight technic
When you want to see the full explenation of the technic you can find it here.
Our dog loves this toy. We also sell them and give our profits to the seeing eye dogs.
We now also make them with Macramé yarn en the results you can see HERE
