The Quilt-EZ Templates.
These are the grooved templates you were talking about. Any machine on the market we have a stylus for the machine. This will attach into the side aluminum extrusion slot of your machine.
Long-Arm templates: These are 13" wide. If you have anything less than 13" left on the last pass of a quilt, then i would recommend looking into the mid-arm templates, noted below. IF you have average of 13", then you will be fine with the long-arm templates.

Mid-arm templates:In the mid-arm templates, the max pattern size is 10". Need to look at the LAST pass of a quilt, how much space is left over to determine if you can use anything larger than 10".
