I agree with other comments; particularly the one about trimming the outer border. Try trimming to 2 in. which would finish at 1-1/2 and then audition one of the lighter blues in the stars and use that as the final border. Audition this final border at 3 in., finishing at 2-1/2 in., which would add symmetry to your borders. Beautiful job on the stars - never an easy job especially when taking care none of the points are chopped off! Thanks for sharing.
