kat,
What if you chose a color... say
pink since the back is pink... and
fmq on all the pink in the quilt?
On the pink rick rack lines, around
the pink flowers, stipple on all the
solid pink areas, etc. There looks
to be enough pink that the quilting
would be evenly spaced over the
surface of the quilt and then the
design would look nice on the back also.
I don't know how difficult that would be,
but it's an idea.
