This pattern was deisgned for those that get colder than most in the winter. Malabrigo Rasta is very warm as it is; the stitch used gives it even more warmth!
While it was designed to fit a smaller frame, the pattern is so basic that it can be followed to fit a larger frame, as well. Just buy an extra skein, if that’s your wish.
Even though Malabrigo was used, any super bulky yarn will suffice.
