So, I had the whole thing ready and laid out on the kitchen floor. The dark blue and the white wool were basted together. Plastic covering the floor, and rags in case of spills. Water boiling in the tea pot. A foil-covered cardboard tube to wrap around, and foil to cover the wrapped cloth. I asked my husband to lend a hand, just in case....
If someone had recorded us, it would be a You-Tube comedy classic. The wool absorbed a LOT more water than I had figured, and we were quickly boiling more, until it started running all over the floor. Working together, we got the hot, wet wool wrapped around the tube. Jeff held it while I struggled to pull cloth tape tightly around. I didn't get it as tight as I had hoped, but we managed to get it all inside a double layer of heavy foil, and it fit in the oven. Many hours later:
