Creative Grids 雙峰合一 13吋 x 7吋 CGR2P1

Finally, a ruler that makes those triangle-in-a-square blocks effortless — the dual peak angles save so much time. Cutting with the keyhole is surprisingly smooth, and the size is perfect for my smaller cutting mat.

The keyhole cut-out is such a clever touch—it makes the rotary cutting feel precise without the ruler shifting around. I’ve knocked out a dozen triangle-in-a-square blocks this afternoon and the 2:1 ratio lines just make sense.

The keyhole cut-out is genius for seeing exactly where my fabric lines up before I commit to the cut, and the 2:1 ratio markings take the guesswork out of triangle-in-a-square blocks. Only wish the ruler had a grippy backing since it slipped once on my mat.
