Вот так можно получить треугольники, не выкраивая их, а просто сшить квадраты:

2. Sew a 1/4″ seam on each side of the pencil line.

3. Cut along the pencil line of each square.

4. Press the seams to the darker fabric.

5. Pair the half square triangles (HST) with other half square triangles (HST).

6. Place one HST over another HST with right sides together making sure the dark sides are over the light sides as seen in the picture below.

7. Draw another pencil line from one corner across the seam to the other corner as seen in the picture below. Now sew a 1/4″ seam on each side of the pencil line.

8. After sewing a 1/4″ seam on each side of the pencil line you will cut along the pencil line as seen below. You will need to make two piles. One pile for the left half and one pile for the right half. You ask why? Well, when you go to sew the HST’s together you will want the seams to seat into each other and that will give you well matched points and seams.

9. Now comes the pressing. Start with the right pile that you made in step 8. Open the seam and press them in a clockwise direction as seen below. Repeat the process for the left hand pile as seen below. These seams will go in a counter-clockwise direction.

Here’s a close-up of the seam that you will be opening up.

10. Trim each unit Hourglass Unite to 3″ x 3″ using the Triangle square up ruler making sure to keep your left piles together and your right piles together.

11. Arrange and sew the Hourglass blocks from the right hand pile into groups of 4 hourglass blocks per sashing unit and then repeat for the Hourglass blocks from the left hand pile. You will need 16 of these Hourglass Sashing Units for the Table Runner and then press the seams open.
