I bought my Sentro machine here!
The Yarn that I used and it worked really well for this project was the Jeans yarn linked here (lion brand yarn with 50% discount), also I used a long circular needle as well 6mm and 30″ long, you need a long one because it will be easier to remove stitches from the Addi or Sentro knitting machine! I found out that using needles to cast off stitches of your panels is the easiest way!
Also I used 3 different sizes of crochet hooks, that’s always good to have, bigger ones to make the work and smaller ones for faster finishing of tails, etc…
The link for the full tutorial is here, I hope you enjoy it, let me know in the comments when you try it :)!
