I have a Janome 6600P. I have quilted full size quilts under it with no problem. I did stitch in the ditch. On a large lap quilt I echo quilted it and satin stitched around the pansies. I used the even feed foot with no problems. I like it for garment sewing and for piecing quilts. It runs quietly and I have had it over 3-4 years and never had a problem with it. It has never been in the shop.
