WOW!!! These quilts are BOTH lovely!
BUT - as you ask (and not becasue these quilts are not great!) - I would consider the scales of the fabrics you choose, in any project I try to combine large florals (or prints) with smaller designs and plains, plaids, dots, marble blenders etc.
I do also like to add a bit of variety and I add a fabric that includes a second colour like a multi coloured print which features blue, to a lesser or greater extent.
Keep up the great work - love the quilts!!!
