Wow! Fantastic, G! WTG, girl!!! You got it now! #2 looks super! All 3 look great, but by having the darkest border as in #2, it adds depth, warmth, hominess, connection, balance and brings the white stars forward the most!!! It actually coordinates best with the colors of the flowers you chose too. Oh, now I see that you eliminated the alternate blocks so this makes a quick quilt even quicker!! Great!!
p.s. yes, QuiltnNan is right! The navy blue one on pt. loses all the depth you had with the darkest border of #2. Can you see how the lighter navy color washes away the effect?
