I just don't seem to really get this quilting part. Can i do stitch in the ditch on my sewing machine and then handquilt a design? I am making a flannel throw with trees made from triangles put on raggy style. I wanted to do something around the trees. This quilt is going to my son's girlfriend's parents in East Asia. He is meeting them for the first time and wants a special gift. Thanks so much for any advice you can give.
