Nancy, I did the straight line quilting with a walking foot on the 401A, the FMQing with a darning foot on the Bernina (my 401A doesn't like FMQing). The secret to no puckers/folds is taking care with the basting. I use curved safety pins when I'm machine quilting; thread when I'm hand quilting.
The applique was done by hand...Wonder Under fused, then buttonhole stitched with #12 perle cotton.
I haven't gifted the quilt yet...the family hasn't been to church since the baby was born.
