مسطرة مثلث 15 درجة من Creative Grids CGREU1

I’ve been using this ruler to piece Dresden plates, and the laser-cut lines make lining up those 15-degree angles effortless. It’s sturdy enough to handle repeated rotary cutting without slipping. Finished a 48-inch fan block in no time.

Finally a ruler that lets me chain-piece 24 triangles in one go without stopping to re-position. The 15-degree angle markings are dead on, and my 48-inch Dresden Plate came out perfectly flat.

I was surprised how quickly the quarter-circle came together with just 6 triangles. The markings are clear and stay put, though I wish the ruler had a non-slip backing for cutting slippery fabrics.
