13 Block Lap Size Quilt Tutorial {Old School BOM Final Layout}

Because we made 2 blocks in April during the Old School BOM, I wanted a layout that would accommodate all 13 blocks that were made during the Old School Block of the Month. This layout is a very straight forward solution to having 13 different blocks that finish at 12″ square, so I thought I’d share what you’d need if you want to recreate this 52″ x 72″ finish.

You’ll need:

  • (13) 12½” unfinished (12″ finished) blocks
  • 1¾ yards of background fabric

Cutting Instructions

From the background fabric, cut:

  • (2) 12½” x WOF strips
    • From each strip, subcut (2) 12½” squares [for a total of (4)] and (3) 4½” x 12½” rectangles
  • (3) 4½” x WOF strips
    • Subcut (8) 4½” x 12½” rectangles [for a total of (14)]
  • (8) 2½” x WOF strips

Piecing Instructions

  1. Arrange your (13) blocks on your design wall 5 rows, alternating between 3 and 2 blocks per row, as shown in the assembly diagram above.
  2. Using the (4) 12½” background squares and (14) 4½” x 12½” background rectangles, sew the blocks and background pieces together to make 5 rows. Press seams toward the background fabric.
  3. Trim the selvages from the (8) 2½” x WOF background strips and sew them together along the short ends to make one long, continuous strip. Find the average measured width of your 5 pieced rows, and trim the long strip into 6 sashing strips using the average measured width, approximately 2½” x 52½”.
  4. Alternating between a sashing row and block row, sew the quilt top together. Press seams toward the background fabric. The quilt top should measure approximately 52½” x 72½”.

TIP: When sewing the sashing and rows together, I used a few pins to make sure everything stayed lined up. It’s useful to know that the blocks overlap one another by 4″. For the purposes of pinning, I measured and marked  4″ offsets to use to line up the edge of the next block row with along the raw edge of sashing.

  5. Greta layout, thanks for sharing! I really like how each block has room around it so it can stand on its own.

    Yvonne, You saved the day…I have a collection of (16) 12-1/2 inch blocks and was undecided on a layout for them. Love your Old School BOM final layout and will now be able to finish this quilt top. Thanks for sharing and kicking off my 2022 in a positive mode!

I really appreciate the time and thought you take to comment, and I look forward to conversing with you. :)
