I take anything larger than crib to a LAer. He looks at the quilt top and then suggests patterns that will enhance the quilting. He does many, many quilts and I trust his judgement more than my own.
For crib/lap quilts, I use a walking foot and straight lines. It is more important to me to get a quilt done than to stress over the quilting.
My great-grandmother and grandmother made many quilts. Most were for everyday use and were quilted with very fine stitchs and all in straight line variations. The only one with curved lines was not used everyday as evidenced by its great condition.
Thank goodness for folks like you who love to LA!
