Say goodbye to the tedious, time-consuming process of marking diagonal sewing lines one by one. The Creative Grids® 9" Seam Guide Tool is a compact, revolutionary marking notion that will instantly speed up your piecing workflow. Designed to be exactly 1/2-inch wide with a dashed center line, this tool allows you to mark two perfect 1/4-inch sewing lines on either side of a diagonal with just a single placement. At 9 inches long, it is the absolute perfect size for working with 5-inch pre-cuts (charm squares) and smaller patchwork units. Featuring the patented Creative Grids non-slip grip, this guide locks firmly onto your fabric, ensuring your marking pen never pushes the ruler out of alignment.

Why Customers Love This Tool
Customers love the 9-inch Seam Guide because it directly solves the frustration of marking half-square triangles. Marking a center line and then measuring a quarter-inch out on both sides is exhausting when you have dozens of blocks to prep. This tool cuts that prep time in half. Quilters particularly adore this 9-inch version because it is perfectly scaled for charm pack projects. It is small enough to keep right next to the sewing machine, and the non-slip grip guarantees perfectly straight stitch lines, resulting in blocks that square up beautifully every time.

Frequently Asked Questions
How do I use this tool to make half-square triangles? Place the tool on the wrong side of your fabric square, aligning the dashed center line directly from corner to corner. Draw a line along both outer edges of the acrylic. You now have two perfectly spaced 1/4-inch sewing lines! Stitch directly on those drawn lines, cut down the center diagonal, and press open to reveal two perfect HSTs.
Will this fit across a 5-inch charm square? Yes! The diagonal of a 5-inch square is approximately 7 inches. This 9-inch seam guide gives you the perfect amount of overhang to easily align and mark charm squares without the tool falling short.
Is this used for cutting or marking? This specific tool is designed primarily as a marking guide for your fabric pens and pencils. While it is made of durable acrylic, its narrow 1/2-inch width makes it better suited for drawing stitch lines rather than applying heavy downward pressure with a rotary cutter.
