You can use the single-pronged transfer tool to cast off in two ways: in front of or behind the sinker posts (gate pegs). The first is quick and easy, the second gives a better finish.
An e-wrap cast on is a very easy and quick method that can produce a nice closed edge. Needs a bit of practice to get it even, but you can make it looser if you want a stretchier edge.
It is a good idea to create a wonderful knitting workspace for your new knitting machine to ensure successful knitting. You will need a table and chair, good lighting, space for tools, yarns, accessories and patterns.
