BTW non quilters rarely notice if the seams don't line up they are in so much awe that they don't see what you do. We work so closely with our fabrics that we KNOW what is off .. most of the rest of the world does not adults as well as children.
Glad you posted. I cant wait to see the NEXT ONE! (grin) I know your dying to start that project). Hey how about a four patch posie (posey) with that other fabric? easier to line up and still a similar effect but only four square cuts.
