I'm doing the Farmer's Wife Sampler Quilt and the blocks are supposed to finish at 6 1/2". All mine have finished at 6 1/4" (except 1 or 2). I figure since they're all the same size I can adjust the sashing and border sizes to fit my blocks. If they were all different I'd be concerned. If yours are all the same, the quilt should work out just fine. Good luck!
