I just went to the Hancock's of Paducah website. They have a Kona black 44" wide and a Kona black 60" wide, each for $2.49 per half-yard. I wonder if there is a difference between them? The 60" width says it's broadcloth; the 44" width does not.
I have some blue Kona here that I bought from the local LQS, and I'm pretty sure it is broadcloth. The weave is a little different. Will have to go measure it and see if it's 60" wide. (It's been so long, I can't remember.) Nope. Just found it, and it's 44" wide.
Oops: And I went back to the Hancock's website and see where a full yard is $3.98! (when you go to order)
