To really speed things up, make 8 half-square triangles at a time. You’ll find the tutorial here.
If red isn’t a favorite of yours, consider substituting fabric of another color. Royal blue would be striking, as would just about any other strong color. A rainbow of colors would be stunning, too. Mottled, low-contrast fabrics allow the overall pattern of the quilt to take center stage.
The finished quilt by designer Marianne Elizabeth is 52 1/2″ x 71 1/2″.
