Unroll several sheets from the roll. You can tear them off and tape back on the roll when done, or just leave them attached to the roll. I left mine attached to the roll and unrolled enough so that the roll rested under the sewing arm out of the way.
Cut a piece of cutaway backing stabilizer to be wider than the hoop all the way around and at least as wide and tall as the piece of paper towel. Using spray adhesive (I like Madeira’s MSA 1000 because it works well but doesn’t smell bad), spray the backing and stick it to the back of the first sheet. If you need more room to get the entire paper towel in the hoop, you can embroider on the second sheet so the first will be inside the hoop. When finished, just discard the first (unembroidered) sheet.
Hoop the backed paper towel in any hoop that fits the machine embroidery design. I thought a magnetic hoop would be ideal, but did not have the right size for my design, so I used a round, regular hoop. Pop it on the machine, and let it sew! I slowed down the embroidery machine a bit, just in case.
When finished, remove from the hoop and cut the backing to the same size as the sheet of paper towel. I did not cut around the Catwoman machine embroidery design the way I would for garments.
You may need to use more spray adhesive so the corners are stuck together before you hang it up.
When I finished the design shown here, I was going to carefully iron the paper towel to remove the hoop marks, but was called away before I could do it. By the next morning, the marks had disappeared all by themselves!
