This is the VERTICAL row version of the horizontal row Blanket Cardigan pattern found here: https://www.ravelry.com/patterns/library/blanket-cardigan-3

While this pattern does call for a lightweight/size 3/DK yarn, for the vertical blanket cardigan pictured here, I used three strands of Red Heart’s NEW It’s a Wrap yarn held together. https://hearthookhome.com/red-heart-its-a-wrap-independen...

I did stagger the colors so that they would transition slowly, which necessitated the use of nearly SIX cakes for the size large. If you would like a similar effect at a much less cost, you could use three separate strands/colors of size 30 crochet thread to get the same effect. Make sure you check your gauge if you decide to deviate from the lightweight/size 3/DK yarn suggested in the pattern.
