I spun up 4 oz. of hand-dyed BFL last year, and I thought it would be just enough for a hat. I was right! I had less than 10 yards left when I was done. This will be a birthday gift for my MIL. Because of my FIL’s surgery next month, they are spending more time up North this winter (and she hates the cold) - they usually go South in January and stay til spring.
The pattern is Diamond Ridges by Kristy Ashmore. It’s a thick, heavy hat. The pattern called for DK weight, and my yarn was slightly thicker than that. It ended up a little large, but not uncomfortably so…it just doesn’t need to stretch much at all to fit a woman’s head. It has plenty of stretch to fit a larger head, though. I did substitute alternating fpdc/bpdc for the ribbing and decreased by about 7-8 stitches.
