Tri-Recs Without Specialty Rulers

"Tri-recs" units, usually a triangle in a square rather than a rectangle, are a common feature in patchwork quilting. They are easily made using Tri-Recs Rulers, but if you don't have specialty rulers or need a size to big for your ruler, here's the secrets to making them easy peasy with regular ol' cutting methods.

As mentioned above, triangle in a square or tri-recs units are usually made with a specialty ruler set. Sometimes, though, you might only need a few tri-recs and not want to invest in a new ruler just for that, or, you might need a larger triangle in a square than your ruler allows. That’s where this tutorial comes in— Tri-Recs WITHOUT a specialty ruler!

If you are looking for how to make triangles in a square WITH rulers or your AccuQuilt, check out this post

Let’s Get Started

*Tri-recs Without Specialty Rulers units are made two at a time, due to the need to have reversed triangles for the "wings."
**Please note that this method uses more fabric than the specialty rulers, so plan accordingly if working from a pattern written for using specialty rulers. For example, my upcoming pattern, Dogwood Blossoms, is fat-quarter friendly, but if using this method, you might need more like a third of a yard instead

Materials: 
-Two fabrics, a fat quarter of each
-Your favorite cutting ruler (such as a 8.5 x 24 inch)
-Rotary cutter and mat
-Iron
-Sewing machine set up for piecing

Formula:
Squares= 
(Finished tri-recs size + 1/2 inch) x (finished tri-recs size + 1/2 inch)
Rectangles= (Finished tri-recs size + 1/2 inch) x (1/2 finished try-recs size + 1 inch)

Directions

Goal: 6.5 x 6.5 inch tri-recs unit

4) Line up your ruler diagonally from mark to mark on the rectangles and cut, making two sets of funky triangles that become the "wings" of each tri-recs unit

5) Sew right "wing" onto the first tri-recs unit by aligning the top corner with the center mark on that square and the lower corner with the lower right corner of the square. Sew 1/4 inch from edge of triangle

6) Trim away excess fabric, leaving a 1/4 inch seam allowance. Press wing up into position

7) Repeat steps 5 and 6 with the left wing of the tri-recs unit, then trim up block to measure 6.5 inches square. Be sure to center the upper point of the center triangle and leave a 1/4 seam allowance at all points

8) Repeat steps 5-7 with second tri-recs unit
