Even knowing all that, Ryan still asked for a Slytherin scarf. Maybe he just knows he looks good in green. I don't think it's because he hates mudbloods.
The backstory: In For Yarn's Sake we have a shop sample of a Gryffindor scarf. Ryan came to take me to lunch one day and saw the scarf. He really liked it and asked if I could make one. (Incidentally, it's a stockinette tube. Yes darling, I can make that.) I told him I'd be happy to make him one. He asked for Slytherin colors. Who am I to say no.
His good side
I didn't follow a pattern for this because, um, it's just stripes. I cast on enough stitches to go around a 16" needle (50) and worked my first green stipe until it was as long as I wanted. That turned out to be 17 rows. Then I did 2 rows silver, 2 rows green, 2 rows silver. Repeat forever, ending with a big green block. Flatten the tube into a big long rectangle. Add fringe. Ta-Da!
His other good side
The yarn I used was Cascade 128. A 100% superwash merino that knits up nicely to a bulky gauge. I used size 10 needles and got a fabric that drapes but is still dense enough to keep the cold out. The colors I used were silver and army green. It took 3 full balls of the green (I used up every last scrap making the fringe) and just over half a ball of the silver.
Ryan gave me some nice model poses for a while.
And a silly pose or too.
But eventually he tired of sitting in the cold listening to me direct him on how to sit and how to wear his scarf, and the shoot deteriorated.
Ah, true love.
