Square Heart Quilt Pattern

I had a bunch of fabric leftover after making my Half Square Triangle Pillow last week and wanted to make a fast coordinating quilt with the rest of the fat quarter set. Valentine’s day is coming up, so it needed to be a quilt that would come together quickly.

I decided to go with a quilt that was a take-off of my scrappy heart quilt block. The idea is the same, but there are more squares used in this big heart quilt pattern, allowing me to use almost all of the fabrics from my wildberry palette fat quarter set

Precut friendly

This Big Square Heart Quilt Pattern is made of mostly 5-inch squares so it is definitely precut friendly. (You could use a charm pack or a layer cake cut into fourths. (I used a fat quarter set.) You will need a few larger scraps of fabric as the 16 half square triangles start with 5.5-inch squares. (8 colored and 8 white.)

For the best results, you will want to use at least 10 different colors/prints plus a background color for your quilt design.

Make different sized Quilts

The Square Heart Quilt pattern I am sharing today is a lap size quilt, measuring 54 inches by 54 inches. The good news is you can make a larger or smaller quilt just by changing the size of the squares you start with.

  • 3 inch squares = 30 x 30 (use 3.5 for the half square triangles)
  • 4 inch squares = 42 x 42 (use 4.5 for the half square triangles)
  • 5 inch squares = 54 x 54 (use 5.5 for the half square triangles)
  • 6 inch squares = 66 x 66 (use 6.5 for the half square triangles)
  • 7 inch squares = 78 x 78 (use 7.5 for the half square triangles)

Quilting suggestion

I hope to get my quilt top completely quilted and bound in the next few days. I plan to keep it simple and just quilt a quarter inch from the seam lines.

Sewing tips

  • For faster cutting, use a 5-inch square template. (like this 5-inch ruler)
  • Use a scant quarter-inch seam allowance when sewing the half-square triangles. (Gives you more room to trim.)
  • Press your fabric before cutting.
  • Square up all blocks even if they are precuts.
  • Nest the seams when sewing the blocks together.
  • Measure your seam allowances with each new project. (Or every time you turn your machine back on.) I use this seam allowance ruler.

Fabric Amounts needed for the Big Square Heart Quilt

  • At least 10 different colored/print fat quarters for the “heart”
  • 1.5 yards of background fabric
  • 3.5 yards of 42-inch wide fabric for backing
  • 1/3 yard of 42-inch wide fabric for binding

Pattern Notes:

  • wof = width of fabric.
  • Scant 1/4 inch seam allowances are used when making the half square triangle blocks.
  • RST = Right sides together.
  • Chain piecing = The process of sewing blocks of fabric together without stopping between each one. The threads are clipped after all pieces are sewn. This saves time and thread.
  • Nesting seams =  lining up of seam allowance in the opposite direction to reduce bulk. (See this image.)
  • Press the seams to the colored fabric side.

Step 3: Decide Color Layout

Once all your squares are cut, pressed, and trimmed, you’ll want to lay the pieces out on the floor or a design wall to determine the best way to assemble the square for color distribution. (I love my portable design wall for this.)

  1. Covid and the snow (Chicago) has kept people at home and VOILA I have to make 4 or maybe 5 baby quilts! I have 2 in the mailers, one on the machine and I think this heart one needs to be the #4! I make them big enough for Mom to sit there as well (and maybe the family dog….) Think the world will stop spinning if I make it scrappy? It’s really cute! Thanks
    (leaving now to make the Minestrone soup!)
