Grandma’s Lattice Quilt – Free Pattern


Sew up a beautiful lattice quilt with patchwork squares – just like grandma would make! This free pattern is for a generous 77’’ x 77’’ size throw quilt.

This Free Quilt Pattern is Both Jelly Roll and Fat Quarter Friendly!

The best part is that it is both fat quarter friendly and jelly roll friendly. It’s probably my friendliest free quilt pattern yet!

This blog post has been converted to an optional PDF that’s optimized for printing. Find it here. The free quilt pattern in the blog post below is totally free to read, print, and sew! Just hit CTRL +P on your computer to print. The Optimized for Printing PDF download for $3 is totally optional.

And this Quilt Uses Strip Piecing!

You’ll also love sewing this quilt pattern because of how fast and easy it is! I’ll show you my favorite strip piecing method that helps you sew all those patchwork squares in strips first. This quilt piecing technique is so much faster than cutting 2 1/2” squares and sewing them together (which is fun too – I did that for this super scrappy patchwork quilt).

If you love to use your AccuQuilt fabric cutter like I do, I’ll share the optional cutting die numbers to make this pattern Accuquilt-friendly. Using an Accuquilt is optional, but I love it! See all my Accuquilt-friendly quilts. Look under the cutting dimensions below for a list of fabric-cutting dies you may use instead.

I haven’t decided how I’m going to quilt this top yet, but it turned out so beautiful that I knew you would want the free pattern ASAP. I’ll be sure to show you more photos after I quilt and bind it!

All of the fabrics in my Grandma’s Lattice Quilt Pattern are from Heather Bailey’s True Kisses Collection from FIGO Fabrics, except the background, which is Kona Snow.

You probably already have a fat quarter bundle or a couple jelly rolls that you can use to make this easy quilt – just add 2 1/4 yards of background fabric and get sewing today.

So let’s make a beautiful modern traditional patchwork quilt!

Free pattern for Grandma’s Lattice Quilt

You will need:

  • 2 1/4 yards of background fabric (40-42” wide)


  • 1 jelly roll strip bundle + 9 more strips (for a total of 51 strips, each 2 1/2” x 42”)


  • 15 fat quarters of coordinating cotton quilting fabric


  • 3 3/4 yards TOTAL of different coordinating cotton fabrics, cut into 2 1/2” x 42” strips (if you are cutting your own strips, I suggest using as many different coordinating fabrics as possible for a darling scrappy patchwork look)

To finish the quilt, you will need:

  • 5 yards of backing fabric
  • 3/4 yards for the binding
  • a piece of batting at least 81’’ x 81’’

Cutting Instructions for a 77’’ x 77’’ Quilt

The 77’’ x 77’’ quilt requires 18 blocks total.

From the background fabric, cut:

  • 72 squares 6 1/2” x 6 1/2”

If you are using yardage or pre-cut jelly roll strips, you will need:

  • 51 strips, each 2 1/2” x 42”

If you are using fat quarters, cut:

  • 102 strips, each 2 1/2” x 21”

From the binding fabric cut:

  • 8 strips 2 1/2’’ x width of fabric (or your desired binding size)

If you have an Accuquilt cutter, the following dies will work with this quilt pattern:

  • 2 1/2” strip die 55017
  • 6” finished square 55000

How to Sew Grandma’s Lattice Quilt Blocks

Make 18 quilt blocks for the entire quilt. Use a scant 1/4’’ seam allowance for best results.

For each Grandma’s Lattice Quilt Block, you will need five 9-patch blocks.

Use Strip Piecing to Make 90 Nine-Patch Blocks


  • I sewed this Grandma’s Lattice Quilt using fat quarters, so my strips are all 2 1/2” x 21” (I didn’t cut off the selvage)
  • You can use pre-cut jelly roll strips (or 2 1/2” x 42” strips) just as they are or cut each one in half so that your block combinations have more variety
  • Before sewing, sort all of your strips into sets of 3 strips that look good together.

1. Place two fabric strips right sides together.

Sew along one long edge with a scant 1/4” seam allowance.

2. Open the strips and sew a third one to the set, again with a scant 1/4” seam allowance.

3. Press both seam allowances in the same direction.

Repeat to make:

  • 34 strip sets if you are using 21” long fabric strips


  • 17 strip sets if you are using 42” long fabric strips

4. Sub-cut each strip set into 2 1/2” wide pieces. Discard the selvages and any leftover scraps.

If your strip sets are 21” long, you should get 8 pieces from each strip set.

If your strip sets are 42” long, you should get 16 pieces from each strip set.

Cut all of your strip sets into 6 1/2” x 2 1/2” pieces.

You’ll need 270 pieces.

5. Select 3 pieces that look good together. Sew the three pieces together with a scant 1/4” seam to make a 9-patch block.

Press the seams to one side or open, as desired.

Repeat to make 90 nine-patch blocks.

Sew 9-Patches and Background Fabric Squares into 18 Quilt Blocks

1. Each Grandma’s Lattice Quilt Block will need five 9-patch blocks and four 6 1/2” x 6 1/2” background fabric squares.

Arrange the pieces in a pleasing manner.

2. Sew the squares together to make 3 rows.

Then sew the rows together to make an 18 1/2” x 18 1/2” block.

Repeat to make 18 blocks.

Cut 5 of the Blocks

1. Cut 4 of the quilt blocks in half diagonally as shown above.

2. Cut 1 of the quilt blocks in quarters diagonally as shown above.

Sew the Quilt Blocks Together on Point

Quilt Assembly Diagram

1. Arrange the square blocks in diagonal rows as shown in the Quilt Assembly Diagram.

2. Place the half-block triangle pieces along the edges.

3. Place the quarter-block triangle pieces at the corners.

4. Sew the blocks and triangle pieces together in diagonal rows. When sewing a triangle piece to a block, align the square corners and start sewing there. The triangles are a bit smaller than the blocks.

5. Sew the rows together to finish the quilt top. Trim the edges to square the quilt if necessary.

Finishing Grandma’s Lattice Quilt

1. Cut the backing fabric in half and sew it together to make a piece big enough for the back of the quilt (at least 81 1/2’’ x 81 1/2’’).

2. Sandwich the quilt top, batting, and backing together and baste. My favorite basting methods to hold my quilt sandwich layers together are fusible batting or pin basting.

3. Quilt the quilt top as desired.

4. Cut 8 strips of binding 2 1/2’’ x width-of-fabric (or as desired) and sew them together using diagonal seams. Bind the quilt using your preferred method. See how I bind my quilts by machine here.
