Cutting out

Step 1

Cut the patterned scraps into 77 strips, each 2½in x 7in. Don’t worry too much about the accuracy of the length as smaller pieces can be used towards the tapered ends of the diamond block. Keep any 2½in wide offcuts for the coloured border.

Step 2

Cut the solid fabrics into 22 strips each 1¼in x 7in.

Cut the strips of fabric

Step 3

From the white fabric, cut the following for sashing (refer also to the quilt assembly diagram below):

  • Sixteen strips 2½in x 11in (Sashing A on assembly diagram)
  • Two strips 2½in x 14in (Sashing B)
  • Two strips 2½in x 36in (Sashing C)
  • Two strips 2½in x 44in (Sashing D)

Step 4

From the white fabric, cut six strips 2½in x 36½in for borders (see White Border on assembly diagram).

Top tip: To reduce wastage, you can use shorter scrap pieces that taper towards the ends of the diamond shape, but measure against the template to ensure the pieces will be wide enough.

Step 5

Copy the triangle template three times and cut out the triangles. Use adhesive tape to join two triangles together into a diamond shape. Set the other triangle template aside for the moment. Use the diamond template to cut five diamonds from white fabric and then sub-cut as follows:

  • Cut three of the diamonds in half horizontally (you need six in total).
  • Cut two diamonds in half vertically (you need two in total).
  • Cut the remaining two long half diamonds in half to make quarter diamonds (you need four in total).

Step 6

From the binding fabric cut five strips 2½in wide x width of fabric.

Making the scrappy diamonds

Step 7

To make a scrappy diamond you need seven 2½in wide patterned strips and two 1¼in wide solid strips. Lay out the strips in your preferred order and then sew them together using ¼in seams.

Press the seams open as you go.

You should now have a rectangle that’s about 7in x 16in.

Step 8

Fold the pieced rectangle in half horizontally and place the triangle template on top, aligning the short edge of the triangle with the fold.

Trim the overhang down to size. Open up and you’ll have your first scrappy diamond.

How to make a diamond quilt step 2b

Repeat to make eleven pieced diamonds in total.

Top tip: The diamonds have bias edges that can stretch and lose shape easily, so be sure to handle and press with care to avoid risk of distortion.

Sewing the quilt rows together

Step 9

The diamonds are sewn together into diagonal rows, as follows. For the first row, arrange one diamond, two Sashing A strips, one white half diamond and one long half diamond as shown in the diagram (Fig 1).

Pin them well and then sew these pieces together.

The end of the sashing will extend just past the ends of the diamond. When lining up the next piece of the row, offset the ends by ¼in so that the line of stitching meets precisely at the edge of the previous piece.

Step 10

Make the other rows using the same process, following the layout shown in the quilt assembly diagram. Where rows have more than one diamond, use a ruler to trim the overhang down flush with the diamond edge before attaching the next diamond.

Assembling the quilt top

Step 11

When the five diagonal rows are completed, sew them together with strips of white sashing in between each one.

How to make a diamond quilt step 4a

The lengths of the sashing will vary (Sashing B, C and D) – refer to the quilt assembly diagram and the images in this post. See also the Perfect Positioning tip, below.

Perfect Positioning

To line up the points of the diamonds on each row, draw little dots or crosses as markers on the back and offset the row by ¼in. It is worth taking your time lining this up and pinning well to avoid shifting.

Step 12

When all of the sashing has been added, press the quilt top and square this up – it should be 36½in high x 32in wide.

Adding the borders

Step 13

For the inner white border, sew a 2½in x 36½in white border strip to each side of the quilt and press seams open. Sew two more 2½in x 36½in white strips to the top and bottom of the quilt. Press seams open.

Step 14

For the outer coloured border, sew the 2½in wide patterned fabric pieces together until you have two strips that are 2½in x 36½in (Step k). Sew these to the top and bottom of the quilt and press seams open. If need be, trim the sides of the strips flush with the quilt.

Step 15

Sew the two remaining 2½in x 36½in white strips to the top and bottom of the quilt to complete.

Top tip: To reduce wastage, you can use shorter scrap pieces that taper towards the ends of the diamond shape, but measure against the template to ensure the pieces will be wide enough.

Quilting and finishing

Step 16

Assemble the quilt backing from one piece of fabric, or by piecing together left-overs for a scrappy look. Make a quilt sandwich of the backing fabric, right side down, the batting and then the quilt top, right side up. Baste or pin the layers together using your favourite method.

Step 17

Quilt as desired. Trim off excess batting and backing fabric and square up the edges of the quilt.

Step 18

Sew the binding strips together using diagonal seams, placing the ends of each strip right sides together at a right angle and sewing corner to corner. Trim
to leave ¼in seams. You will need at least 180in of binding. Press seams  open, and then press the full length  of the binding in half lengthways.  Use this double-fold binding to bind the quilt.

Upcycled style

As an alternative to using scraps from your stash, you could use small bits of old baby clothes, hankies or bed linen to make a special heirloom quilt. Any randomly sized small bits  of fabric will be ideal for making this project. If using baby clothes, be sure to iron lightweight fusible interfacing to the back of anything stretchy like jersey, prior to cutting, to make it easier to handle.  Cut pieces an extra ½in larger and use a ½in seam allowance instead of the usual ¼in, as this will help the seams lie flatter. Always press the seams open to reduce bulk.
