So, after a trip to Home Depot to get 3/8ths tubing ($8) and sending hubby back to exchange for 1/4 inch tubing ($5) I have the leaders all installed. I'm so stoked!
Oh, and got a call back from the sewing machine place.
Oh, and re-looked through my instructions....and I suspect they DID send tubing, and it is stuffed in the aluminum rails, that are attached to the frame. :oops: But for $5...I'm totally not taking apart the tubes to get to them.
