Love that border! And it really compliments the circular designs formed by the quilting in the main body of the quilt.
Thanks so much for posting the closeup. Getting an echo with templates is indeed hard, even with a foot that works! But the effect is so worth it. And while we stress over those areas where the echo isn't the same or the freehand fill is just a little bit different, most of the time once the quilt is off the rack I have trouble finding those spots.
I take pride in my hand guided work and try to embrace the imperfections and variations that a computer guided set up won't do. You should too, the result is lovely!
