"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.

I have a brand new pattern out called Dogwood Blossoms-- yay! This pattern calls for triangle in a square units, more frequently called "tri-recs" units. It's a pretty quick unit to make with the specialty rulers, but I know not everyone has those. Plus, it's a pretty quick unit to make without the rulers, too! 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
-Two fabrics, a fat quarter of each
-Your favorite cutting ruler (such as a 8.5 x 24 inch)
-Rotary cutter and mat
-Sewing machine set up for piecing
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)
Goal: 6.5 x 6.5 inch tri-recs unit
1) Cut: 2 (two) 7 inch squares and 2 (two) 7 x 4.5 inch rectangles
2) Mark the center point of the top edge of each square, then set aside
3) place rectangles RIGHT sides together. Then, make 1/2 inch in from lower left corner and upper right corner
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
Ta-da!! You are now ready to make Dogwood Blossoms or any other tri-recs using pattern without the specialty ruler!
