I like my quilting to be a 2nd design on the quilt to draw someone 'in' to looking more at it - sometimes it's just an expansion of the quilting pattern, sometimes it draws off of one or more of the fabrics, and sometimes it's specific to the recipient of the quilt and still other times its something totally random that i Like.
You can always do something fun in the negative space of the blocks, sashings, borders, and just SITD your actual stars.
