I love this block. It's also known as the signature block. I am seriously considering starting making a ton of these blocks now and have people sign them when I get married. It's really nice because they have the area in the white to sign. This block was easy-peasy, rotary cut and then machine pieced.
I finally found a selvedge edge that let me know what this line of fabric is (seen previously in C-9 Jane's Tears). It's Free Study Glimmer by Kristine Baerlin, made by Free Spirit Fabrics. I really love the colors of this line, and I really love Free Spirit Fabrics in general.
