Sewing a mosaic #3 quilt block involves using a variety of small fabric pieces to create a visually striking design. Here are the steps to create this block:

Materials:

• Fabric pieces in at least 3 different colors
• Rotary cutter or fabric scissors
• Cutting mat
• Sewing machine
• Thread
• Iron and ironing board
• Quilting ruler

Instructions:

1. Cut fabric pieces into small squares of the same size. For the mosaic #3 quilt block, you will need at least three different colors of fabric.

2. Arrange the fabric squares in the desired pattern. For this block, you will need to arrange the squares into a diamond shape, with the colors forming a gradient from light to dark.

3. Sew the squares together into rows, using a 1/4 inch seam allowance. Press the seams open using an iron.

4. Sew the rows together, matching the seams as you go. Press the seams open.

5. Trim the edges of the block to ensure it is square and the correct size. For a mosaic #3 block, the finished size should be 12.5 inches square.

6. Repeat the process to create as many blocks as needed for your quilt.

7. Arrange the blocks in the desired layout, alternating the direction of the diamond shape to create a dynamic visual effect.

8. Sew the blocks together, again using a 1/4 inch seam allowance. Press the seams open.

9. Add batting and backing to create a quilt sandwich, then quilt as desired.

10. Bind the edges of the quilt to finish.

Congratulations, you have now sewn a beautiful mosaic #3 quilt block!

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″.
