Tula's Premium Collections were her very first for Aurifil, dating back to 2013. They included 12 Large Spools or 10 Small Spools of our variegated hues in Aurifil 50wt. They are truly designed for versatility-- something that makes a huge difference when working with bold print and color as is Tula's design genius. These spools perfectly complement her fabrics and have been doing so for years.
