One of my favorite's is my knee lifts on my Bernina and my Janome 11000! For my longarm my favorite thing that's really not a tool is the "diaper" I made to prevent the batting and quilt top from getting on the floor of my studio. Basically a sheet can be attached to the table and to a free rollar by whatever means you prefer. I used velco hook and loop strips to attach....mine is made of a slick material that nothing sticks to and I love it. Only once did my favorite kitty take a short cut through it and I boogy maned her and she's not done it again!
