I thought I only had one I haven't used-the wavy edge one. Then realized I bought some books that included rulers that I haven't used yet. One is for a wedding ring quilt, another is that black, white and red quilt by Quilt in a Day, and there is another book with one I can't even think of the name at this moment....brain fog is heavy tonight. Basicly I only have boughten normal straight rulers and I use everyone I have regularly. Time to do those someday projects with the rulers included with the books.
