Learn how to make a Mariner's Compass by strip piecing (no paper piecing required)! Robin Ruth has developed revolutionary rulers, books, patterns, and tutorials for her technique. This book includes complete how-to instructions for using the 16-Point Mariner's Compass acrylic ruler. Compass blocks can be made in 16 sizes—even-numbered sizes from 6" to 36" (45-degree angles). Three quilt patterns are also included in the book. Use with the Angle Ruler sold separately. Check out this YouTube tutorial.
