I think what is meant is that you are not required to sign up, but you can do so if you desire. When you get the email, then you download the free pattern. I hope to see pictures from others who are doing the blocks! If you have done a Bonnie Hunter mystery quilt, or other 'quilt along' types of projects, then you will know how encouraging it is to work on a project together. I did lots of Farmer's Wife Sampler blocks on this forum. I'm looking forward to doing this sampler. :-)
