    About the Mosaic Four Patch Quilt Pattern

    I hope you'll have fun choosing fabrics and working on this quilt pattern and its Mosaic Four Patch quilt blocks.

    At first glance, the quilt might appear to be made from a bunch of squares that are sewn together in large sections. In reality, two variations of the Mosaic Four patch block are all it takes to assemble the quilt (see page 2). Blocks are placed on point and surrounded with setting triangles before borders are added.

    The best news... Mosaic Four Patch quilt blocks are easy to make,...MORE and even beginning quilters will be able to complete the quilt pattern with ease.

    Choose a Size for the Blocks and Quilt

    Work through the instructions on pages 2 through 6 to sew a quilt made with 8" quilt blocks that finishes at about 57" x 68".

    Fabrics and Other Materials for the 57" x 68" Quilt

    Change fabrics to suit your needs. Before choosing fabrics, be sure to read through the pattern and look at illustrations so that you'll understand how blocks fit together. Choose a variety of prints, but do keep in mind the size of finished squares in each quilt block. Large scale prints typically aren't the best choice for quilts with small patches, but they can be used in the setting triangles and borders.

    Fabric colors relate to my blocks, yours will likely differ. Pencil-in your changes.

    Yardages are a bit generous, but I always recommend buying a bit extra if possible to compensate for cutting errors and shrinkage... and for any typos I might make.

    Black, used in both quilt blocks and for the narrow border

    • 5/8 yard for blocks
    • 3/8 yard for narrow border (2" wide crosswise strips pieced together)

    Bright Gold, used in Block A

    • 5/8 yards

    Teal Print w/Brown, used in Block A

    • 5/8 yard

    Light Blue Print, used in Block A

    • 1/3 yard

    Red Print, used in Block B

    • 3/8 yards

    Green Print, bluish undertones, used in Block B

    • 3/8 yards

    Medium-Dark Blue Print contrasts somewhat with black, used in Block B

    • 1/4 yard

    Greenish Gold Print, for setting triangles and outer border
    Splitting yardages for those who choose a different fabric for each area.

    • 3/4 yards for setting and corner triangles>
    • 1 yard for borders (using 5" crosswise grain strips pieced together)

      Alternate: Buy 2 yards of a single fabric for lengthwise grain borders and use excess to cut setting triangles; cut (4) 5" wide strips along the length of fabric first -- reserve for borders. Cut squares for setting and corner squares last.

    Backing: 4 yards, depending on configuration, or about 67" x 78" (How to Make Quilt Backing)

    Batting: same as backing

    Double fold binding to finish at 1/4" or wider, about 275 running inches of continuous double fold binding (How to Make Quilt Binding)

    Mosaic Four Patch Quilt Block Variations

    Two variations of the Mosaic Four Patch quilt block are used to assemble the quilt. The quilt blocks are strip pieced, and each block contains only two different strip configurations.

    Blocks are easy to assemble, but it is important to sew with an accurate ​quarter inch seam allowance and avoid stretch when pressing.

    • The quilt is made with 20 versions of Block A, shown on the left
    • Block B, on the right, is repeated 12 times in the quilt.

    Make Mosaic Four Patch 'A' Quilt Blocks

    Make 20 of the type A Mosaic Four Patch quilt blocks.

    Type A Block Cutting Instructions

    The term 'selvage width' strips refers to long strips of fabric cut across the crosswise grain -- from selvage to selvage (How to Rotary Cut Fabric Strips)

    Bright Gold: (6) 2-1/2" selvage width strips

    Teal with Brown: (6) 2-1/2" selvage width strips

    Black: (9) 2-1/2" selvage width strips

    Light Blue: (3) 2-1/2" selvage width strips

    1. Refer to the top left illustration. Sew four strips together...MORE lengthwise in this order:
      • Gold - Teal - Black - Gold
    2. Carefully press seam allowances towards the teal and the black strips.
    3. Square up one end of the strip set and then cut as many 2-1/2" segments from it as possible, likely 16.
    4. Make two more identical strip sets with remaining strips and cut a total of (40) 2-1/2" segments. You will have an extra length leftover when all are cut -- insurance for squaring up and for those little wibble-wobbles that can make some strips too narrow.
    5. Refer to the top right illustration. Create a strip set by sewing four strips together in this order: Teal - Black - Light Blue - Black.
    6. Press seam allowances towards the blue and teal strips. (Note: there's really no way to devise a perfect seam allowance arrangement for this quilt block. Take care when segments are sewn together to create blocks, and when blocks are joined, too.)
    7. Square up one end of the strip set and cut 2-1/2" segments as before. Make two more strip sets and cut (40) 2-1/2" segments.
    8. Arrange two of each segment type as shown, bottom left. Like-segments are flipped around to create mirror images.
    9. Sew the rows together, matching seams carefully. Press the quilt block. The block should measure 8-1/2" x 8-1/2".


      Note: After pressing the first block to verify that its size is correct, you might want to press remaining blocks later, when they are aligned with others -- it might make it easier to press adjoining seams in opposite directions for better match-ups.

    10. Make a total of 20 Type A quilt blocks.

    Make 12 of the type B Mosaic Four Patch quilt blocks.

    Type B Block Cutting Instructions

    Red: (4) 2-1/2" x selvage width strips

    Green: (4) 2-1/2" x selvage width strips

    Black: (6) 2-1/2" x selvage width strips

    Medium-Dark Blue: (2) 2-1/2" x selvage width strips

    1. Refer to the top left illustration. Create the first strip set by sewing four strips lengthwise in this order:

      Red - Green - Black - Red

    2. Press outer seam allowances towards the red; remaining towards the green.
    3. Square up one end of...MORE the strip set. Cut as many 2-1/2" segments as possible.
    4. Make a second identical strip set. Cut a total of (24) 2-1/2" segments.
    5. Refer to the top right illustration. Sew four strips together lengthwise in this order:

      Green - Black - Medium-Dark Blue - Black

    6. Press outer seam allowances away from the green and black; remaining towards the blue (again, there's no true perfect way to press seam allowances).
    7. Make a second strip set and cut a total of (24) 2-1/2" segments.
    8. Arrange two of each segment as shown to create four rows, bottom left, flipping one segment in a pair to create mirror images. Sew rows together. Press now or wait until blocks are joined.
    9. Make a total of (12) Type B quilt blocks.

    Sew Mosaic Four Patch Quilt Blocks into Rows

    The Mosaic Four Patch quilt pattern results in a quilt with on-point blocks, but I've set the blocks on their sides in this illustration to make it a bit easier to visualize placement.

    1. Use a design wall or other flat surface to create seven rows with the two different Mosaic Four Patch quilt blocks. Blocks alternate within each row, but each row begins and ends with a block that has gold corners.
    2. Sew the blocks in each row together, carefully matching seam intersections, but do not sew rows...MORE together -- setting triangles must be added first.

      If you waited to press some seams, now's the time to handle that task, pressing as many as possible in opposite directions before sewing to adjoining blocks.

    Finish Sewing the Mosaic Four Patch Quilt

    How to Cut and Sew Setting Triangles

    Cut Setting Triangles and Finish the Quilt

    1. Cut (4) 12-5/8" x 12-5/8" squares of greenish gold print for setting triangles. Cut each square in half twice diagonally to create four triangles each with the straight grain on their longest edges. (Two triangles will not be used -- mark the long edge as straight grain and keep for scrap quilt blocks.)
    2. Cut corner triangles by dividing (2) 6-5/8" squares once diagonally.

      How to Cut Setting and Corner Triangles

    3. Place a setting triangle at each...MORE row end as illustrated. Place the smaller corner triangles at the for corners of the quilt.
    4. Sew setting triangles to their row ends, matching their 90-degree sides with the straight side of each row. Press seam allowances towards the triangles and trim excess 'dog ear' fabric created by seam allowance at angled edges of the triangles.
    5. Sew rows together. The quilt top should look like the quilt on page 1, minus its borders.
    6. Fold corner triangles in half along their longest edge. Center and sew a triangle to the four corners of the quilt. Corner triangles are usually a bit oversize and corners may need to be squared up. Do that now or wait until after the quilt is quilted.
    7. Press the quilt top.
    8. Create an inner border from 2" wide strips of black fabric. Measure and sew to the quilting using your favorite method or my quilt border instructions.

      Beginners -- do not measure border length along the sides of the quilt. Follow my instructions and the borders will help square up any inconsistencies or skewed edges.

    9. Press seam allowances towards the borders.
    10. Use 5" wide strips of greenish gold to sew outer borders (add the long borders first). Press seam allowances towards the borders.
    11. Press the quilt. Mark for quilting if necessary. Sandwich the top with batting and backing and baste by hand, with safety pins (for machine quilting) or try a fusible basting product. Quilt the quilt and apply easy mitered binding with your pre=made binding strips.
