A flat tip ruler MUST be used. Use a Creative Grids 60 degree ruler, or use the template in the pattern to mark a pointed-tip ruler to cut triangles without the point on the top for the proper seam allowance. Follow the directions in the pattern for ruler placement to cut the diamond. The seams will nest and the triangles at the ends will match. If it doesn't make sense on the first read-through, just go ahead and start at the beginning, follow the directions and look at the photographs when reaching that point in the pattern. The flash of understanding will only be topped by the thrill of completion!

Unsew the seams at the arrows

Cut off 1/4 to 1/2 inch parallel to the edge.

Sew back together. Adjust as necessary.

• Ruler - We use the Creative Grids 60 degree ruler, available at your Local Quilt Shop. 
• Yes, you can use triangle rulers other than the Creative Grids. A pointed tip, when aligned to the edge of the fabric, will produce slightly (1/4'') smaller triangles. This is not a problem with cutting or construction (except for the Swirl as stated above), but the same type ruler (pointed or flat tipped) must be used for cutting the entire project.

• Want to use a 30° ruler instead of a 60° ruler? Yes, someone asked, but, It won't work without a bit of geometry and math. 
• CAUTION: High School Geometry lesson.
• It takes six 60° triangles to make a whole six-sided hexagon. Six times 60° equals 360° circle. That is the basis of the Triangle Frenzy patterns.
• If a 30° triangle ruler is used, it will take twelve pieces to make a 12 sided polygon or dodecagon. Twelve times 30° equals 360° circle. 
• So there are twice as many pieces and the outside edges won't fit together without some extra pieces to fill the gaps at the edges.
• OR, one edge of the 30° ruler will have to be aligned along a line perpendicular to the stripe of the fabric. Then cut two symmetrical pieces or one piece with two placements of the ruler. End of lesson.
