I just made a doozy of a mistake. I'm making a Bonnie Hunter "Pineapple Blossoms" quilt out of blues. If you make the version with sashings out of a different colorway, it forms a secondary pattern. I selected a red print. When I cut the strips last week I misread my cutting directions and cut the sashings 1/2 inch too short. After assembling the blocks, I decided I really liked the all blue scrappiness, so I counted out my blue 9.5" strips and I have enough for the sashings! I have enough of the white/blue print I used for the pineapple corners in the block to cut cornerstones, so I may not have to buy any additional fabric.
