Love your S@S, and I notice you used a different alternate block, as I did. I quilted it with an edge to edge design, about 12" wide, but that was on a longarm, and the recipient loves it.

You might have to draw the outline on the quilt to follow a design like that - I use Frixion pens as they iron off.
