Karen's instructions for loading a quilt on a 3 rail frame are really good. I have a Grace EZ3 floor frame and used that to learn how to load and then start quilting on my frame. The one thing you will need are leader cloths for the 3 rails, if they are not included with the frame you were gifted. Here's a link to a leader cloths at Amazon

Also quilting in a floor frame is a bit different than quilting in a hoop. With the lap hoop you start around the middle, on a floor frame you will start at the bottom border and work your way upwards.
