Waste Yarn Cast on
You will find that some patterns ask for the Waste Yarn Cast on method. This is sometimes referred to as provisional cast-on and that is exactly what it is, it’s temporary. You mount the waste yarn first to make it the recipient of your loose loops so that you can remove it later and have your “good” yarn available for a cast-off that matches your other end. If you’re confused not to worry I will explain and demonstrate.
Google defines provisional: arranged or existing for the present, possibly to be changed later. Well, no maybes. In this cast it is being changed for sure.
Below are the written instructions with pictures and step by step video.
