I love seeing the various jigs, fixtures and contraptions that craftspeople invent to speed their creative tasks, and one great thing about the internet is people aren't shy about sharing them. But nothing drives me more nuts than when they show you the jig, show you part of the operation, then skip ahead to the end product without showing you what the heck happened in between.
Case in point: Up top is Artist Ellen Nielsen's Big Pom. That's the end product. Below is the video showing the contraption she uses to make it, but the video ends without showing the crucial final steps. Do you have any idea what those steps are? (You'll want to scan through the video, to see the intermediate steps, as it's six minutes long.)
While no answer exists on Nielsen's website, I noodled around on the web a bit and believe I've figured it out. If you want to be a hero, see if you can guess what she did without hitting the jump. All others, click on through to see a video that may provide the answer.The video below shows how to make a small pom pom:
As you can see, it hinges on creating a row of loops (or in this case a circle of loops, as it goes around the center of the donut) that you can pass a single length of yarn through to knot the center together. There is a secondary outer row of loops created during the wrapping process, and that row of loops is severed, transforming it into the pom pom's tips.
So based on this, my guess is that once Nielsen's done wrapping all of the yarn on her device, she simply passes a cord through, say, the bottom row of loops, knots that up, then cuts the top row loose.
