there are plenty of patterns out there but if you are going to use a pattern from a published book, be sure to email them and get permission... we are not supposed to do this... the patterns from quilter's cache are public information EXCEPT for the 'starred' names... and they are the blog owner's designs and require her permission to use...I use the one below and i NEVER refer to it or display without the designer's information.. Book is entitled Rings That Bind...

this is simpler to learn than most just because of the solid arc in this version...but she has many other variations in the book...
