Sewing a square star quilt block involves piecing together several fabric squares to create a star pattern. Here are the steps to follow:

Materials:

• Fabric squares in desired colors and patterns
• Sewing machine
• Thread
• Rotary cutter or scissors
• Cutting mat
• Ruler
• Iron

Instructions:

1. Cut out 16 fabric squares that are all the same size. You can choose the size depending on your desired finished block size.

2. Choose 4 squares that will be the star points. Fold each square in half diagonally and iron to create a crease down the center.

3. Arrange the 4 star point squares and the remaining 12 squares in a pattern that creates a star design. Place the star point squares in the corners, with the folded creases all facing towards the center.

4. Sew the squares together in rows, starting with the top row. Sew the two squares on either side of the top star point square together, then sew the star point square to the middle square in the row. Repeat for the bottom row.

5. Sew the two remaining rows together by first sewing the two squares on either side of the middle square in the third row. Then sew the third row to the second row.

6. Iron all seams flat, then sew the top and bottom rows to the middle row to complete the block.

7. Trim the block to the desired size, making sure all edges are straight and even.

8. Repeat the process to make as many blocks as needed for your quilt project.

By following these steps, you can create a beautiful square star quilt block that can be used as a component of a larger quilt or on its own as a decorative element.

This is a great technique for making half square triangles that eliminates the need to directly manipulate the stretchy bias of the triangle. It utilizes two easy to cut squares producing two half square triangles.

 

On the back of the lighter fabric, draw a pencil line, diagonally from corner to corner.

 

Stack a pair of light and dark squares, right sides together. Sew a 1/4 inch seam allowance on each side of the line.

You will end up with something like this.

Now cut along the diagonal line.

 

Press the seam together to set the seam. Then press towards the darkest fabric.

To trim the block to the exact size line up the diagonal 45°angle with the ruler on your seam.

And then carefully trim your block with a rotary cutter.

 

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″.
