Linda Delagrange, I have done several small quilts that I have quilted on Embroidery Machine. I have a rose machine so all of mine have to be 4x4 but the same princile applies. you have to baste your quilt very well so as not to shift. Take all three layers and open your hoop so it will fit easily than tighten hoop. you have to place the design in the hoop with your templete to make sure you have it in the right place and I used verigated machne quilting thread on top and bottom. I had to adjust my tension and I would do a sample of all three layers first. Takes a lot of in and out of the hoop but the results are stunning.
Have not and will not tackle a big quilt. Have done just a lap quilt.
Hope some of this helps you
