“naturalely” i ran out of yarn, so i inserted a couple of rows in a very light lavender yarn which interestingly matches an undertone in the main yarn, even though they’re not even close to the same material, nor the same gauge. i think the main yarn is actually too hard to be a good chemo hat. it certainly wasn’t the most fun i ever had crocheting a cotton yarn, though i like the pattern (modified at the brim start; original has trebles all the way down).
