First of all, I have a BIG commercial 15 needle machine. I couldn't hoop the case, so I used spray glue to glue my hoop to the suitcase, and put 2 pcs. of heavy cut away under. I had to stand there and hold the suitcase the entire time while it was stitching. I would have never tried this with a reg, sewing/embroidery machine as one would have to put it down each time to change the tread colors. With my 15 needle machine, I could just hold onto it and let it stitch, and it would change the colors for me so I could just hang on to it. This was all trial and error, but it was my case and if it didn't work, I felt it was okay. I would NEVER try to do this for a customer. Good luck if you decide to give it a try.
