Top tip:

With your solids, it doesn’t matter which way up you cut them, but if your print fabric is directional then you will need to take care to cut it correctly. The easiest way to do this is to keep your WOF strip folded in half, meaning that you cut two triangles with each cut

Assembling the quilt

Step 1 Pair your 4in squares together into colour combos as shown to prepare your HSTs. The amount of HSTs you’ll need of each colour combo is shown – each pair of squares will make two HSTs, so you will have some leftover where there are odd numbers.

Step 2 To make the HSTs, take a pair of squares and place one on top of the other, RST. Mark a diagonal line on the wrong side of the top square.

Step 3 Stitch ¼in either side of the marked line and then cut apart along the marked line.

Step 4 Open out the units and press. Keeping the 45-degree line of your ruler aligned with the diagonal seam, trim to 3½in square. You will now have two HSTs like this one.

Step 5 Repeat with the rest of the 4in squares to make the total number of HSTs.

Step 6 Pair your rectangle triangles together into colour combos as shown to prepare your HRTs, making sure that they will be orientated correctly with the seam running the right way when they’re sewn together.

Step 7 Sew each pair of triangles together to make the total number of HRTs.

Step 8 Assemble the HSTs and HRTs into blocks as shown, referring to the photo for colour placement.

Step 9 Sew the units together in rows, then sew the blocks together into rows. Finally, sew the rows together to complete the quilt top.

Quilting and finishing

Step 10 Press the quilt top well. Make a quilt sandwich by placing the backing fabric right side down, the batting on top and then the quilt top centrally and right side up. Baste the layers together.

Step 11 Quilt as desired. Susan quilted around each diagonal shape and used a free-motion stippling design on some solid sections.

Step 12 Sew the binding strips together end-to-end using diagonal seams. Press the seams open and trim away the dog ears. Fold in half lengthwise, WST, and press.

Step 13 Sew the binding to the right side of the quilt, folding a mitre at each corner, then fold the binding over to the back to the quilt and hand stitch in place to finish.
