To sew a Corner-square Triangle (CST), place a square in the corner of a fabric piece, RST. Draw a diagonal line on the wrong side of the square, referring carefully to figures for direction. Sew along the diagonal line. Trim the seam allowance to ¼in and press the piece open to complete.

Step 2

Finishing the quilt top

Step 1

Mountain quilt layout diagram

Referring to the quilt Layout Diagram, join the bottom left and bottom right sections of the quilt, carefully matching seams. Then join the top section of the quilt to finish the quilt top.

Quilting and Finishing

Step 1

Cut the backing fabric in half across the width. Remove the selvedges and sew the two pieces together using a ½in seam. Press the seam open.

Step 2

Press the quilt top and backing well. Make a quilt sandwich by placing the backing fabric right side down, the batting on top, then place the quilt top centrally and right side up. Baste the layers together using your preferred method.

Step 3

Quilt as desired. Annie Seaboch quilted geometric lines in a repeating triangular pattern, to echo the sharp points of the mountain peaks. Trim off the excess batting and backing fabric and square up the quilt.

Step 4

Sew the binding strips together end-to-end using diagonal seams. Press the seams open and trim away the dog ears. Fold in half lengthways, wrong sides together, and press.

Step 5

Sew the joined binding strip to the right side of the quilt, creating a neat mitre at each corner. Fold the binding over to the back of the quilt and secure temporarily with pins or binding clips. Hand stitch or machine stitch in place around the edge to finish.
