I got inspired to knit a sweater 2 days ago (yep, I finished it in 1 day!). Here's the original idea, from PICKLES:

I used size 11 dpns for the armholes (cast on 24 sts), moving to size 15 circs (increasing to 48 sts), then size 19s for the chunkiest stitches (72 sts). I also chose to move from 1x1 to 2x2 to 3x3 rib instead of staying with 2x2 like they did.
I used 4 recycled yarns held together: white wool, cream wool/angora, white/gold cotton, and light green mohair.
They also have a pattern for the 'lavender jacket':
