Sew Half-Rectangle Triangles
A few days ago, on 22 January, I showed you quilt designs using this wonky block.
Caroll Drudy of Attic Window Quilt Shop liked my designs and tried making the block. She reported, "I had to make those rectangles several times before I got them to come out right."
Now, I think it would be great if you were to make a quilt or two using this block. And I don't want you to have trouble with the rectangles; so I'm going to show you how to sew them.
I am going to assume that you already have a favorite method of making half-square triangles and just show you how to make the half-rectangle triangles.
For this block the rectangles are twice as long as they are wide. This means that for a 6"x6" block the rectangles would have a finished size of 2"x 4". For a 9"x9" block the rectangles would have a finished size of 3"x6".
Note: The two rectangles are not the same; they are the mirror image of each other. This means you will need mirror image triangles as well.
1 The triangles are made two at a time.
Cut the fabric diagonally starting 1/4" down on one side and ending 1/4" up on the other. I've drawn a line on the back of the fabric above to show were the cut goes.
The two triangles above are identical. They are not mirror image.
This will give you 4 white triangles. Which is enough for 2 blocks.
You need to cut 2 green triangles and 2 mirror image green triangles as well.
2 A green triangle and a white triangle sewn together make a rectangle.
The long sides are the same length and will line up exactly.
Sew a true 1/4" seam, not a scant one, along the long sides.
3 The rectangle needs to be trimmed.
You now have a rectangle that is 2 1/2" x almost 5".
You need to trim equal amounts off each end of the rectangle to make it 2 1/2" x4 1/2".
To finish the block you need half-square triangles. For 6"x6" blocks you need 2"x2" and 4"x4" half-square triangles, finished size. For 9"x9" blocks you need 3"x3" and 6"x6".
There is more than one way to make half-rectangle triangles. I'll show you a second way in my next post.
