Making Half Square Triangles:

Here is an interesting YouTube video:

 

Now give it a try:

To make half square triangles, start with two squares 7/8” larger than your finished size.

Example: If you are making finished 2” squares (2-1/2” unfinished), you will cut squares measuring 2-7/8”. If you are making finished 3” squares (3-1/2” unfinished), you will cut squares 3-7/8”.

 

Place fabrics Right Sides Together, draw a line diagonally from corner to corner. Sew 1/4”  on each side of drawn line. Cut on drawn line. “Roll” seams open or as specified in your pattern. You will have two half square triangles.  The half squares triangle should measure your unfinished size requirement EXACTLY.

If you find that your piecing is not “measuring up”, start with 1/8” - 1/4” larger sized squares. After you have completed the steps above, square up the piecing by using a ruler. Also, if you do not have a 1/4” foot as a guide, you may use a ruler to draw additional lines 1/4” from the original drawn line as a guide for sewing. Note: You don’t really need a special ruler, any “square up” ruler will work.

Making Quarter Square Triangles

 

To make Quarter Square Triangles, start with two squares measuring 1-1/4" larger than what your finished size will be - (If you find your piecing is not measuring up - start a bit larger maybe 1-1/2" and then square up when complete.)

For instance, if you want your Quarter Square Triangles to measure 3 inches finished, you would begin this process with at least two 4-1/4" inch squares (or larger and square up.)

Next put your two blocks right sides together, and draw a diagonal line from corner to corner.  This starts out the same way you make half square triangles.

Sew 1/4 inch away from both sides of your mark, as you would in making half square triangles.

You now have two half square triangles. Here is how you turn them into quarter square triangles.

 

     

 Take the two pieces, and put them right sides together. However, this time you have to pay attention to the colors.  When you put them right sides together, alternate the colors.  In this example, the red would be under the green color on one side, and the green color under the red on the other side.

Draw another diagonal line - this time going from right to left, or opposite of however you did it the time before.

Again, sew 1/4 inch on both sides of your line, and then again cut them apart on your marked line. Roll seams.

When you open your triangle, you will have a quarter square. (Two squares will make two quarter square triangles.)

 

Tips on squaring up. Determine what your UNFINISHED size is. Divide it by two. When you square up, use that measurement to mark the center. The example above is an UNFINISHED square of 3-1/2". Divided by two would would make the center measurement 1-3/4". The ruler has the 1-3/4" squared up to the center. Also, the ruler is placed on the diagonal and corners should center at the 3-1/2" marks on the perimeter of the ruler. I sure hope this makes sense. Square up the two sides, then turn, and repeat with other two sides. Any questions, please feel free to contact me!

Tips for sewing strips (or rows of blocks) together:

 

· Cut strips accurately.

· Pin together so ends of strips meet, pin center and pin evenly. (This is very important as your feed dog pressure can change the way your strips are sewn, causing strips to wave.)

· Use a seam roller to press seams open. Press with iron using up and down motion.

· Also, another tip is to sew strips in opposite directions (see arrows). This will, again, balance the pressure from the feed dogs to create nice straight strips.

This also works for sewing rows of blocks together, make sure to pin at the intersection when sewing squares or blocks together!

What is the difference between “finished” and “unfinished”?

 

The "unfinished" size of a quilt block includes the seam allowance.

The "finished size" does not include the seam allowance, as it is the “finished” size when sewn in a quilt.

Does that make sense?

 

Please feel free to contact me if you have any questions, problems, or concerns.
