Kathy, I like Kona black too - I just ordered 10 yards from Hancocks of Paducah - they are having a 20% off sale until the 12th if you are interested, so I got my 10 yards for about $36. It's what I will use for AOTH.
Do you wash that too? I didn't think it would run, but then I haven't put as much in a quilt as AOTH will need.
