Very pretty block. I also have trouble with the size of my blocks. I am currently using a Bernina Aurora 440/QE but my blocks still are off a bit. I backed off the pressure on the presser foot and it helped some, not a lot. I think it is the nature of sewing two pieces together and ironing them. This does not lend itself to accurate block sizes just because of the fold when we iron the seams. That's my excuse and I'm sticking to it. LOL.
