Now for threading the Upper Looper...it's the needle with the purple thread in the above photo. It's a breeze to thread!!!
That jigger drink to calm your anxiety attack is for threading the LOWER LOOPER. It's the needle under the Upper Looper with the pink thread. If or when it comes un-threaded....one jigger is not enough.
When changing threads, cut the threads between the thread guide and the thread guide plate. Pull the threaded needle threads until the tied knots reach the needles. Cut the knots out and thread the left and right needles with the new color. Thread the LOWER Looper first, then the UPPER Looper. (my tip....tie a small tight knot in the old/new threads...it will slide through the large eye of the loopers).
