Kaleidoscope Ruler - The Triangle Ruler from Quilt in a Day.
Instead of making templates to cut triangles, we suggest using the Quilt in a Day Kaleidoscope Ruler for block center triangles. It will make piecing the Tide Pools quilt together easier and more exact.
Made from heavy gauge acrylic, 1/4", 1/2" and 1" lines. Two colors for easy reading. Laser precise and 1/4" lines provided for seam allowance.
