Key Features and Benefits
The Deco Tumbler Ruler is crafted from clear acrylic with easy-to-read black lines and markings, similar to other Sew Kind of Wonderful rulers. Its design includes reference points that assist in squaring up your blocks after sewing, ensuring your finished pieces are uniform and accurate.
One of the standout benefits is its compatibility with the no-pins curved piecing method.

The ruler's size and shape are optimized for cutting multiple layers, making it efficient for batch cutting.
How to Use the Deco Tumbler Ruler
To use the Deco Tumbler Ruler, start by folding your fabric as you would for any rotary cutting task. Place the ruler on the fabric, aligning the marked lines with the grain or fold as needed. Use a rotary cutter to trim the fabric along the ruler's edges to create your tumbler shapes.
After cutting, you'll have pieces ready for curved piecing. Follow the pattern instructions for sewing the curves, using the ruler's reference marks to square up your blocks after stitching. This ensures your blocks are the correct size and shape for the final quilt top.
