This is an intermediate pattern, written for size L/XL.

For XXL/XXXL, your starting chain would be 137. Your numbers for front right, sleeve base, back, sleeve base, front left would be 24-16-57-16-24. Your initial sleeve count would change from 57 to 65, and your final sleeve count would change from 20 to 25.

I used approximately 5 1/2 skeins of the yarn.
