One-Block Wonders Book by Maxine Rosenthal & Joy Pelzmann. Sequel to the original One-Block Wonders book but with a new spin: six quilt projects, more fabrics, new effects, methods for endless variations and gallery of 12+ quilts.
Create dramatic new design effects: hollow cubes, cubes sliced open, cubes tumbling into borders / becoming edges.
Make quilts using multiple fabrics: you learn to choose the right fabrics, with photos showing the original fabrics and finished quilt ( eg asymmetrical prints quilts using two colourways ). Still no Y-seams! All easy straight line piecing.
