all of my quilts are double sided, the one I just got back is 2 of Bonnie Hunters mysteries, the other is the one I made with the 50 fab stars paper piecing book with a heavily pieced reverse...my long armer doesn't have any trouble quilting them, but we both understand that if a needle hits a joint with a lot of layers in it the stitch will not be the same size as those surrounding it.
My dear jane was double sided and I hand quilted it.
Quit worrying and start creating.
Double sided quilts half the cost of sending a quilt out to be long armed
Halves the storage space required.
And they are Always beautiful on the bed...
