Back when I was working contracts that sent me to work with families and children on various military bases in Europe; I most enjoyed working with children during arts and crafts. At one of the bases in Germany, the middle school kids were making potholders. I worked closely with the base staff person on that project, but even so...it was impossible to get the kids to complete the technique above that saves your potholder weave from totally falling apart.
Look closely at the loom in the first shot and the three potholders above in the second. You'll notice the technique. It's a simple one that I'm very grateful for. In fact, you couldnt even begin to make the rug without it. All you do is:
Leave the end loom notch empty for each potholder you're making
Weave your every other loops over and under the remaining notches with the stationary loops
When you're finished with your over and under loops, go to the empty notches (8 that will hold 4 loops) and weave your loop THROUGH each loop, NOT over and under.
This allows you to remove the potholder from the loom WITHOUT losing all of your hard weaving work. It means you don't waste any time trying to recreate the weave you've lost as you try to finish the potholder and remove it from the loom. I can generally make one potholder every 30 minutes or so.
With the rug, you leave the potholder unfinished and then you are able to hold them and attach them together.
As excited as I was about attaching two together; is as bummed as I was about trying to get the four corners on the inside of the rug to come together in a neat and flowing manner. After many attempts, I resigned myself to the spaghetti of loops that came together in very bizarre ways in the center. I'm still not sure what the best approach would be. The outside border came together much more easily, and looked okay, but not as neat as I'd have liked. I guess it's time to "google" or "phone a friend" for help.
Even so, Mom was excited and so pleased when she saw it. One side definitely looks better than the other, but it wasn't bad for a first effort. I'm not surrendering. I'll keep you posted.
