Find out how to make a puff quilt with our guide to sewing this cute chevron puff quilt pattern. Have fun mixing modern fabric prints set with cool white triangles, then opt for a soft and snuggly backing fabric and you’ll stitch together light, puffy chevrons to make a lovely modern make for any nursery. You’ll be making each individual “puff” square separately, then sewing them together, so while this puff quilt may take you a couple of days to make, it’s also seriously soothing to piece together.

What is a puff quilt?

If you’re wondering “what is a puff quilt”, it’s basically a quilt in which each block is filled with toy stuffing before the quilt is finished, giving it a puffy effect. Puff quilts are also sometimes known as biscuit quilts or bubble quilts. It’s made a little bit differently than a traditional quilt. Instead of sandwiching 3 layers together (the top fabric, backing fabric and wadding in the middle), you stuff and make each quilt block separately, then sew them together to make a bigger quilt.

Prepare the half square triangles

Step 1

Place one 5in square of white  fabric to a 5in printed square RST. Using a ruler, mark a line down the diagonal. Then sew a ¼in seam allowance on either side of the line. Cut on the line and open to reveal your two half triangle squares (Fig a).

Iron towards the coloured fabric and trim the overhanging corners (Fig b). Repeat with all 40 of the white squares until you have 80 half square triangles.

Step 2

Place one HST on one 4in square muslin, wrong sides together. Line up the corners (Fig c).

You will see that since the top piece is larger you will have to make a crease in the top fabric (Fig d).

Sew with a 3/8in seam allowance down the edge, over the crease. Pivot at the corner and repeat with the next two sides. Leave the fourth edge open. Take a handful of the poly-fil and stuff it in the pocket. Then make your crease and sew the final side shut (Fig e).

Repeat until you have all 80 puffs sewn.

Assemble the quilt top

Step 1

Now the fun part! Arrange with the puffs until you get the pattern the way you like it. Rotate the HST puffs to achieve the chevron pattern (Fig f). Line up the puffs so you have eight puffs in a row and ten puffs in a column.

Step 2

Sew the puffs together one at a time, pushing the puffs RST and using a 58 seam allowance to ensure the puffs’ seams don’t show. Sew each puff together until you have ten rows of eight.

Step 3

Push two rows of puffs together and match up the seams of each row, placing a pin in each intersection. Then sew the rows together with a 58in seam allowance. It’s easiest to sew the rows together in sets of two, then in sets of four.

Step 4

Prepare a quilt sandwich with the remaining 4in squares of patterned fabric, high loft batting and white fabric (Fig g) to make the cornerstones.

Repeat with the two 4in x 30in strips and two 4in x 23½in strips of muslin, batting and white fabric to make the borders. Baste the edges of these sandwiches. Sew in the same direction down each set of long edges to avoid stretching the fabric diagonally.

Step 5

With RST sew the four squares to the ends of the long borders (Fig h).

Step 6

Turn the quilt over and pin one short border to the short side of the quilt, RST (Fig I). Sew with a 58in seam allowance. Repeat with the second short border. Then pin one long border to the long side of the quilt, lining up the end squares with the short borders. Sew with a 58in seam allowance. Repeat with the second long border.

Step 7

Cut a low loft batting a couple inches larger than your quilt top and a backing fabric (we used lovely soft minky fabric) a couple of inches larger than the batting. Layer these together with the batting in the middle. Smooth each layer thoroughly and then pin liberally each side of the quilt. Baste around the edges of the quilt using a 38in seam. Trim excess batting and backing.

Step 8

To bind, sew your fabric strips end to end on the bias. Press in half lengthwise and use to bind your quilt.

Step 9

Using a large embroidery needle and floss, tack down the quilt in the puff intersections—it is not necessary to tack every intersection, every set of two will be sufficient. Knot the floss on the top of the quilt and trim the ends close to the knot.
