Using instructions found here I finally made myself a niddy noddy and the best part is that it only cost $3 for all the supplies! Happy!
It's not much to look at and it has a funny name but this device will make a huge impact in my spinning. Usually, I spin some singles and ply them together onto a bobbin. I let the yarn sit on the bobbin overnight. Then, I wrap the yarn around my dining room table chairs. This step is a major drag. It involves walking around the table, wrapping the yarn over the tops of the chairs which I've measured out to be a yard apart. If it's a small amount of yarn (80 yards or less) I just use two chairs. A larger bobbin full gets the whole do-dah. Then I lay down while the room spins because I just walked in circles over and over and over. Then I give it another day before setting he twist. To do that, I remove the chair yarn and place it in hot water for 20 minutes. Then I wring it out carefully, towel-dry, and hang it over a clothes hanger in the shower, with a full spray bottle hooked over the bottom to weight it down. Simple. You have yarn.
The niddy noddy allows me to skip everything after the plying! I can wrap the yarn around the noddy from the bobbin and let it sit there. I can steam set the twist while the yarn is on the noddy. I can let the yarn dry on the noddy. This is the best $3 I ever spent. No picture because it is ugly.
By the way, the guy at my local hardware store was a real jerk about cutting the PVC for me. I only wanted one 18-inch length and four 6-inch lengths. I guess it was a drag for him to cut it up but I asked on the phone first if it was possible. I think I just got the wrong guy when I went in there. Oh, and he cut the 18-inch one long. This is actually a major pain because the 18-inches is a half-yard. Yards are the way yarn is always measured. Now I measure in 20-inch increments. That means math. Math is hard. Less happy now...
