I'm also a ruler folding convert. I have a lot of fabric and am still slowly getting it all ruler folded. I like it better than the comic book board version - not to mention it's cheaper than buying comic boards. I also love the way it looks on my shelves, all nice and tidy
I haven't made and i spy quilt yet. One of these days. I have been collecting tidbits to make one someday. I just don't have a reason to make one yet. Maybe by the time my kids have children... hopefully that will be a long way off. My oldest is only going on 12!
