The wave and loopy line decorative stitch on the Espire covers a 1 1/4 - 1 1/2 inch spread using the large size. These are the largest ones I have found so far.
I did find that all the basic stitches that are under the Utility Stich menu can be adjusted in stitch length and width (up to 7 mm) but these are all the smaller designs and not really suitable for quilting (other than stitch in the ditch). Just wish the stitches under the Decorative Stitches menu were more adjustable. It would make the machine so much more powerful for quilting.
