Winnona, I'm sure you won't miss it and when Terri compiles the list, I'm sure she will flip through this thread to see if there is anybody missed.
For the center that is on point...measure from side to side, but it will have to have corners added to it to make it "square". I would highly recommend that it happen in the 1st round...no later than the 2nd or your quilt will end up big enough to cover your house! That is unless you want to add the corners yourself and have that be your center...(the center as shown=on point with corners added to make it square)
