I used my 7X11 hoop for some monogramming of more scarves, and while I was checking the space it would use, I forgot to move my machine up to allow for the hoop to move back and it knocked up again the clamped on light (heavy duty),. When I began the stitches I didn't realize that the center was off until the last letter. I was able to take off the top of the hoop to get the rest of the letter on the scarf, but couldn't get the center back properly. Then it dawned on my maybe if I cut my machine off and let it rest a couple of minutes then see what happens... IT WORKED!!!! WHEW!!! It's back to center again. Thank the good Lord!
