How big will the quilt be? 2" strips will finish up to 1.5" squares, which for me would be pretty small. If I were going to do this on a bed size quilt (twin or larger), I would probably cut 2-1/2" strips, which would finish to 2" squares. I'm thinking the quilt shop owner likely used precut strips for her quilt, which would be another indication that 2.5" would be okay.
