Thanks to the recommendation from this forum, I purchased my first CREATIVE GRIDS rulers (to add to my June Tailor slotted rulers) - and I **LIKE** them!!!! Since I couldn't decide which one, my dear husband bought me three - a 3 1/2" x 18 1/2"; a 6 1/2" x 24 1/2"; and a Two-In-One 12 1/2 Square It Up & Fussy Cut Ruler. All are non-slip, easy to read, nice thin lines. I'm in quilting heaven!!!
