Modifying the start because I hate finishing and I got messed up doing it the first time and had to start over anyways.

Collar: CO 100 and work ribbing with smaller needles.
1st row after collar: switch to larger needles, pm, k1, pm, k13, pm, k38, pm, k13, pm, k1, pm, knit to end.
Then use short rows to make the top back portion (the part where the pattern is knit flat). Instead of the first and last kfb, make the short row one stitch longer.

Skip the CO. Then continue the rest as written. Sizing down because my gauge is big. According to my calculations, the size M (37 inch chest) should actually be a 40 inch chest with my gauge.

Colors: Purple, tan, brown, gold, red, olive, steel blue. I have roughly equal amounts of each. Stripes: Following the duplicate pattern but divide number of rows by 2 and then decreasing the tan, red, and olive sections (so every color has roughly 50 rows).

ROUND TWO
I redid my stripe scheme in a google doc HERE. I’m going to use the original number of rows divided by 3. Also not doing the lazy collar modification because it made the sweater pull funny.

Aug 6-7: frogged, washed the skeins to straighten them, and rewound. Ready to cast on again!

Sept 4: Cast off body. Much happier than the first try - it actually fits!

A year later: finally pulled this out again to work on sleeves. Unfortunately the tan color was basically all used up on the body, so now I’m just totally fudging the stripe pattern. Might run out of more colors so the sleeves will be fraternal.
