Creative Grids 15 inch naadgeleider CGRSMN15

I’ve been using this 15-inch seam guide to mark diagonals on my 10-inch squares, and the slotted center makes it so easy to draw a precise line with a mechanical pencil. Stitching a quarter-inch on each side afterward is incredibly straightforward.

The slot down the middle is genius—I can mark my seam lines with a mechanical pencil without any shifting, and the 15-inch length covers way more than my old short ruler. Sewing a quarter inch on each side has never felt this precise or this easy.

Finally, a ruler that won't slip while I'm marking the diagonal on my 10-inch squares—the slotted center works perfectly with my mechanical pencil. Sewing a quarter-inch seam on each side is now effortless. I wish I'd bought this ages ago.
