What Is the Sew Square 8 Ruler?
The Sew Square 8 is a square ruler that measures 8 inches by 8 inches. It's specifically designed for squaring up quilt blocks and cutting curves with ease. Unlike standard rulers, it often features markings and angles that cater to curved piecing, making it a favorite among quilters who use the Quick Curve Ruler (QCR) system.
This ruler is part of Sew Kind of Wonderful's line of tools that complement their patterns. While the QCR Mini Ruler is great for smaller projects, the Sew Square 8 is ideal for larger blocks and ensures your finished pieces are perfectly square before you assemble your quilt top.
- Check the ruler's markings for 45-degree and 60-degree angles, which help with trimming and squaring.
- Use it with a rotary cutter and mat for best results.
How Do You Use the Sew Square 8 Ruler?
Using the Sew Square 8 is straightforward. After sewing curved pieces together, place the ruler over the block, aligning the seam lines with the ruler's markings. Trim the excess fabric to square up the block to the desired size. This ensures each block is uniform, making assembly easier.
For patterns like Plant Life, which uses the Wonder Curve Ruler, the Sew Square 8 can be used to square up the finished blocks before sewing them into rows. Always follow the pattern's instructions for specific trimming steps, but the Sew Square 8 is a reliable companion for any curved block.
- Always press your seams before squaring to avoid distortion.
- Use a rotating mat to trim multiple sides without lifting the ruler.
Why Choose the Sew Square 8 Over Other Rulers?
The Sew Square 8 offers a balance of size and precision. Its 8-inch dimension is large enough for most quilt blocks but still manageable for smaller hands. The ruler is made from durable acrylic, ensuring it stays flat and accurate over time.
Compared to generic square rulers, the Sew Square 8 is tailored to the needs of curved piecing, with specific markings that align with Sew Kind of Wonderful patterns. This reduces the risk of miscutting and saves time, as you don't have to guess where to trim.
- Look for rulers with non-slip grips to prevent shifting.
- Store your ruler flat to avoid warping.
