YC Quilter

I have pieced this "Simply Woven" pattern from Moda, but can not for the life of me figure out what to do for the quilting! All the seams are pressed open, so SID won't work. One LQS suggested Echo quilting inside each colored piece. Unless I try to free motion quilt that, it would be way to much turning of the quilt on my DSM. I thought of breaking the 12 inch blocks into 6 in sections. Basically I can't reach a satisfactory idea. I'd appreciate any suggestions you might have![ATTACH=CONFIG]533717[/ATTACH][ATTACH=CONFIG]533716[/ATTACH]
