I probably spend almost as much time researching ideas as quilting them. I usually think about the "theme" of the quilt and work that idea around to get me started and search for other quilts that are similar and look at how they are quilted and decide whether I like it or can do something different. Pinterest is great for ideas and options and I save ideas that I browse through if I'm at a loss or recollect anything I've seen previously. Like stitch678 and bearisgray I test ideas out on the duralar plastic sheet with water soluble markers on the quilt top or print a b/w picture that I draw on to refer to for quilting later. I've also used You Doodle, a free app I downloaded on my iPad you can import a picture of your quilt and draw on it to try different designs. Lots of great tutorials on YouTube as mentioned earlier and inbox jaunt I've used several times for motifs. I think the key is to just relax and pick something to get quilting, often inspiration strikes just as I step up to the quilting machine!
