That's a great resource, Patrice. Thanks I bookmarked it. I've embroidered on my Janome 9000 the full sandwich many times. You have to make sure the design you pick is somewhat of an outline only so the back looks decent. One other hint is when you're doing the full quilt you need to make sure none of the quilt drags on the embroidery. Otherwise it will be off. Some people put the machine on the floor so the weight is distributed all around. I did o.k. spreading the quilt out on my table. But, I never did queens or Kings that way. I think the larger quilts would need to be done on a very large table or on the floor.
I love embroidery machines...they can be like mini long-arms.
