Are you asking about the 2017 BOM, Halo Star Medallion? Just as this year, I use the fabric I own, that I've selected over time, no specific fabric line. When asked "whose fabric is that?", I say "Mine--I bought it, I own it, I shop in my closet." The idea of using one fabric line only in a queen-size scrappy looking quilt isn't my style. Hope that answers your question.
The photo shows the fabrics I started with, I added more from fat quarter or smaller pieces over the year in all those same colors. The Focus fabric is at least 10 years old.
