I went to the site www.quiltblocksgalore.com and looked at the attic window and tried that but couldnt get my corner to come out so I actually thought about cutting squares and making my triangle pcs that was so it would be more like sewing on a square instead of a triangle..but I am not sure but I am not sure how much of the panels to cut down to get them to look right someone said about losing most of the white so if I do that then will lose some of the picture but I guess it wont make much difference since it is a window scene..(Right)
