It took me a while but I did it!!! I didn't have a 4" embroidery hoop. Not a single margerine tub or any 4" dish in my extensive collection of little dishes. I was about to give up when I measured the top of my large iced coffee plastic cup from Dunkin Donuts, VOILA! I cut off the rim of the cup and it worked perfect. Then I wondered what kind of cardboard you used.... I tried an empty cereal box and it also worked! I used a polyester batting and followed your instructions and I have a real cute little folding thread catcher!!! I took a couple of pictures and I will post them in the picture file. Thanks so much Elle for posting this neat tutorial!!!!!
