Being a crocheter and not a knitter meant this was tough.
I scoured the internet for a suitable pattern. On the way I saved every image I could find of Amy that had that scarf. I not only looked at patterns for cable scarves but also looked at patterns that were supposedly made to look like this scarf. Amy has two different knitted red scarves she wears, which apparently confused a few pattern makers. The closest I found to the scarf I wanted was this pattern by Amanda Throm and while it taught me what the standard was for knitting a cable, it didn't match the pictures I had of Amy's scarf. In the end I found nothing that would work.
There was only one thing left to do. Make up a knitting pattern for my first knitting project.
It actually wasn't too hard. I still have no idea how to cast on (I just crocheted a chain the length I needed and picked up the stitches from there), but once I understood the concept of knit and pearl everything else was easy.
So here's my version of Amy's super long, thick, red, cabled scarf. The pictures are of the scarf after a full year and a half of abusive use including being yanked on and dragged around by a toddler, so yours will probably look nicer. I'm not a knitter so I don't know how to properly format the pattern, please forgive any errors. Since making this I've decided that I don't like knitting so this will probably be the only knit pattern you'll ever see on this blog.
Amy's Pandorica Scarf
Yarn: 2-3 skeins Vanna's Choice Cranberry (or any worsted weight deep red of your choice)
Needles: Size 15
Cast on 24 stitches
*Purl 3 knit 18 pearl 3 turn around purl 24 turn around* repeat 4 times
purl 3 knit 3, knit 3 onto a different needle, bring forward, knit 3, knit 3 onto a different needle, bring back, knit 6, purl 3 turn around
*purl 24 turn around purl 3 knit 18 pearl 3 turn around* repeat 3 times
pearl 24 turn around
pearl 3 knit 3 onto a different needle, brink back, knit 9, knit 3 onto a different needle, bring forward, knit 3, pearl 3 turn around
Repeat until scarf is desired length and finish off. On Amy it could loop once around her neck and still reach mid thigh. It's a very long scarf! Add 3 tassels on each end, one on each corner and one in the middle. This should make the ends reach the tops of the knees.
Tassels: Take three 12 inch lengths of yarn, fold in half. Insert crochet hook into wrong side of fabric, hook yarn and pull the lengths through far enough to make a loop. Take the ends and pull through the loop, then pull ends until loop tightens.
