Half Rectangle Triangle Tutorial
This tutorial is for Half Rectangle Triangles or HRT’s. This will add another tool to your quilting toolbox and hopefully you will be able to create some fun modern quilts using the HRT.
This tutorial will result in 4.5 x 6.5″ final block size so that you can easily follow along to learn this technique but, ANY SIZE rectangle will work as long as you use the same size rectangles.
2 – 5 x 7” pieces of fabric
Fabric Marking Pen/Pencil
Rotary Cutter & Mat
1. On wrong side of one piece of fabric, draw a diagonal line from the upper right corner to the lower left corner of the fabric.
3. Lift the top piece and rotating slightly match the upper right corner to the upper left corner of the bottom piece of fabric. Match the lower left corner of the top fabric to the lower right corner of the bottom fabric. If desired, pin lightly to hold in place.
4. Using the diagonal drawn line as your guide sew seams ¼” on either side of the drawn line.
5. Using your rotary cutter and ruler cut along the drawn diagonal line.
7. Now you have two HRT’s ready to be used.
Note: Unlike Half Square Triangles, your diagonal line will be in the same orientation on both of your finished Half Rectangle Triangles no matter how you turn it. To make a set of Half Rectangle Triangles with a diagonal line in the opposite direction you will have to reverse the above steps.
Directions for Opposite HRT
1. On the wrong side of one piece of fabric, draw your diagonal line from the upper left corner to the lower right corner.
2. Place the two fabrics right sides together with the marked fabric on top.
3. Lift the top piece and rotating slightly match the upper left corner to the upper right corner of the bottom piece of fabric. Match the lower right corner of the top fabric to the lower left corner of the bottom fabric. If desired, pin lightly to hold in place.
6. Open each new rectangle and press your seams open. Square up to 4.5 x 6.5″ for a final block size of 4 x 6″ when sewn together.
As with Half Square Triangles, Half Rectangle Triangles can be used in countless arrangements to make fun and interesting quilts.
Here is a glimpse of a quick quilt top that was put together to show the versatility of the HRT! We hope you enjoy playing with this block and come up with some fun new quilt designs.
