Like a frame is designed to complement a photo or painting, a quilt is not complete with out its frame, the binding. Binding nicely applied is even, has sharp mitered corners, and the quilt fills the binding.
In The Quilt Show video below, Julie Cefalu demonstrates a technique to make sharp mitered corners and another technique for a nice finish. Add these techniques to her previous video and you are all set to perfectly bind your next quilt.
Although the video is made demonstrating the techniques on a domestic machine, the same techniques can be used when stitching the binding to the quilt using a longarm.
