Continuing our “block party” in celebration of National Quilt Month, artist, designer, quilt maker and Spoonflower Ambassador Andrea Tsang Jackson of 3rd Story Workshop will be showing you how to make a heart quilt block from her Express Quilt. This beginner-friendly quilt project is made with Spoonflower’s Cotton Poplin and Fill-A-Yard®, but any of our quilting-weight cotton fabrics will work great. This is the third of our four-part “block party” series, be sure to tune in next Friday for the final post. By the end of the month you’ll have all the blocks needed to make your own mini-wall hanging or pillow!

Andrea: This heart block from my Express Post quilt uses the versatile technique of “stitch-and-flip,” also known as “snowballing corners.” This version makes 5″ finished hearts and with the border, the block measures 9.5″ (24.5 cm) square. You can use scraps or the recommended fabric requirements for the whole #ExpressPostBlockParty project.

How to Make a Heart Quilt Block

Step 1. Prep Your Heart Block Fabric

Heart fabric:

  • 2 feature fabrics (two halves of the heart): (1x) 3″ x 5.5″ (8 x 14 cm) rectangle of each

Background borders:

  • (2x) 2.5″ x 5.5″ (6.5 x 14 cm) rectangles
  • (2x) 2.5″ x 9.5″ (6.5 x 24.5 cm) rectangles

Background:

  • (2x) 3″ (8 cm) squares
  • (4x) 1.25″ (3.5 cm) squares

Fabric for one heart block

Step 2. Make The Heart Quilt Block

Mark a diagonal line on the back of each background square.

Place a 1.25″ (3.5 cm) background square on top of each feature fabric rectangle in the upper corners, right sides together. Sew along the marked lines.

Trim off the corners 1/4″ (2/3 cm) away from the stitch lines. Press the seams toward the background. This will make two halves of the heart.

Place the two 3″ (8 cm) background squares at the bottom of each half, right sides together. Pay careful attention to the direction of the diagonal lines; they should form a “V”. Sew along the marked line.

Trim off the corners 1/4″ (2/3 cm) away from the stitch line. Press the seam toward the background.


Sew two halves together with a scant 1/4” (2/3 cm) seam allowance. Press the seam toward the darker fabric or press the seam open.

Step 3. Make The Background

Use a scant 1/4″ (2/3 cm) seam allowance for optimum accuracy!

Add the side borders by joining the 2.5″ x 5.5″ (6.5 x 14 cm) background rectangles to the right and left of the heart. Press the seam allowance away from the heart.

Add the top and bottom borders by joining the 2.5″ x 9.5″ (6.5 x 24.5 cm) background rectangles to the top and bottom of the heart. Press the seam allowance away from the heart.

The finished block should measure 9.5″ (24.5 cm) square, and can be inserted in so many of your future quilting projects!

    The instructions for constructing this heart block are excellent. Thank you so much.

    You’re like this geometry genius! Andrea, I want to do a quilt entirely with the hearts. I’m also thinking it should have some creative separating borders especially on diagonals. Would you consider coming up with this as a separate pattern. I love this heart so much. Still trying to wrap my peabrain around how to make even one block. Lived for the day this was posted. Love the Express mail quilt too!
