My "short arm" Singer 91-15 machine is a reconditioned commercial
machine with a 9" throat area. Using pantograph stitching designs
up to 5 1/2" tall, and with my 10" Gammill solid oak table (30" wide)
I can do quilts up to 90" in width. Of course, designs are not as
elaborate as with the Long Arm machines, but for under $2000 I am
in quilter's Heaven with all the projects I can quickly finish!
