Thanks so much for your reply! I would be interested to know if they fray as well. I have only sewed a close zigzag but I can see how that would be difficult on something like this...I really like how this turned out and how you used the picture to cut out your shapes. I am doing a mountain scene, a friend's view from her house and had her son send me a picture of it. I'll post mine when I'm done. Thanks for the inspiration!
