It is based on the book Milliefiore Quilts by Willyne Hammerstein and is a gorgeous quilt. The cover quilt is the one that I am working on. There are Facebook groups and pinterest pictures of different versions of this quilt, which makes it even more fun.
I have completed one round and love the process. I am still trying to figure out if I love the way that I am doing the English Paper Piecing. I am using glue, which makes one part of the preparation just zip along. I started using the 3/8" templates, but am using the templates with the 1/4" seam allowance as I find the 3/8" seam allowance too much for the smaller pieces. I have gone through a variety of threads but am now using mettler embroidery weight thread with thread heaven for my piecing. It nearly disappears and I have many fewer problems with it than with the others I tried (Bottom Line, Masterpiece and Aurifil). Right now I am using a stitch called "the flat back stitch". There are many explanations of the stitch, but you can see a video here at DIY addict.
I am now on my second rosette and enjoying the process a bit more. I think I have gotten more comfortable with the pieces and the flat back stitch. There are two Facebook groups for the Millefiori -La Passacaglia quilt and one for the New Hexagon Book-Millefiore group. They are wonderful resources for learning more about the process.
I'll post on this as I complete rounds. My plan is to make a smaller quilt and I think I have narrowed the size on the layout page. I will soon figure out exactly the rounds I need to and make more plans for this fun quilt. It's exciting to begin something like this and I am enjoying the planing process. To say that I'm nervous about completing the edges would be an understatement, but I have plenty to do before I get there, so I am not focusing too much on that (ok, maybe that's a lie).
