Just my opinion, once I figure out the pattern repeat, and depending on how much fabric I have, blocks needed divide to check the quantity that I can get. Thats on the poseys, have come up with about a 8 inch block but if ran 2 pattern repeats together could make bigger blocks. Not sure what K being refered to?
Probibley a tutorial or blog avaiable for more info.
Happy Quilting :)
