The Sawtooth Star Quilt Block pattern is a classic design that has been used for many years in quilting. This tutorial will guide you through the process of creating this block using simple and easy-to-follow steps.

Materials needed:

Fabric (at least two different colors)

Sewing machine

Thread

Rotary cutter

Cutting mat

Ruler

Step 1: Choose your fabrics

Choose at least two different fabrics that complement each other well. You will need one fabric for the background and another for the star. You can also choose additional fabrics for the star points if desired.

Step 2: Cut your fabrics

Using your rotary cutter, cutting mat, and ruler, cut your fabrics into the following pieces:

Background fabric: Cut one 4.5-inch square and four 2.5-inch squares

Star fabric: Cut one 4.5-inch square and eight 2.5-inch squares

Star point fabric (optional): Cut eight 2.5-inch squares

Step 3: Sew the star points

If you are using a separate fabric for the star points, sew them onto the star fabric squares using a quarter-inch seam allowance. Press the seams towards the star fabric.

Step 4: Assemble the star points

Place two star point squares on opposite corners of the star fabric square, right sides together. Sew along the diagonal edge using a quarter-inch seam allowance. Repeat with the remaining star point squares on the other two corners.

Step 5: Trim the star points

Using your rotary cutter and ruler, trim the excess fabric from the star point seams, leaving a quarter-inch seam allowance. Press the seams towards the star points.

Step 6: Assemble the block

Place the four background fabric squares and the star block right sides together, aligning the edges. Sew the blocks together using a quarter-inch seam allowance, taking care to match the seams as closely as possible. Press the seams towards the background fabric.

Step 7: Trim the block

Using your rotary cutter and ruler, trim the excess fabric from the block to create a 8.5-inch square. Take care to keep the star points centered and straight.

Congratulations! You have now completed the Sawtooth Star Quilt Block. Repeat these steps to create as many blocks as you need for your quilt. This block pattern can be arranged in various ways to create different quilt designs. Have fun experimenting with different color combinations and layouts to make your own unique quilt.

How to Resize Quilt Blocks:

The first step in modifying any quilt block is to decide on the size of your finished quilt block. You can come to a decision based on a number of factors: doubling a pattern, cutting your pattern in half, or choosing the size based on your available fabric.

NOTE: When working from a pattern’s cutting instructions, make sure you remove the seam allowance before doubling or tripling the size. For instance, if your pattern calls for 3-1/2″ squares, first you’ll subtract the sum of the seam allowances (1/2″), double the finished block size (from 3″ to 6″), and add the seam allowance back in (1/2″). So, when all is said and done, you will cut a 6-1/2″ piece of fabric.

Resizing Square Blocks:

Square blocks are the easiest to resize. Simply add to your finished block measurement. For example, if you’d like your finished block to be a 4″ square, you’ll need to cut a 4-1/2″ square of fabric.

Resizing Rectangular Blocks:

Similarly to the square, for rectangle blocks, you’ll add to the length and width measurements of your finished block. If you’re doubling block that measures 3″ x 4″ in your quilt, you’ll cut a 6-1/2″ x 8-1/2″ rectangle of fabric.

Resizing Half-Square Triangle Blocks:

When you want to change the size of a Half-Square Triangle block, add 7/8″ to the desired finished block size. To make a 4″ finished block, you’d cut 4-7/8″ squares.

Resizing Quarter Square Triangle:

Since there are two cut lines and two seam lines in a Quarter-Square Triangle block you’ll need to add 1-1/4″ to the desired finished block size. For a finished block that’s 4″, you’d cut your squares 5-1/4″.
