Welcome to the Board from Peoria, Arizona. Think you'll find out after hand-quilting a twin size that you will really need muscle power to tackle a king size. Unless you learn to quilt in a frame and also how to quilt in different directions. I'm hand-quilting a queen-size in a hoop right now and that thing sure does get heavy! I'm working on the innermost of three borders and can only work for a few hours before my arms and back start "talking to me," and I have to rest for an hour or so before I can continue. But then again, I am no youngster and my age might have something to do with it! I have no plans to hand-quilt something this large again - unless I do the quilt as you go method. LOL
