Cutting out

Step 1

Cut the print fabric as follows:

  • Eight (8) 3in squares (for section 2 on the templates).
  • Sixteen (16) 3½in squares. Subcut in half on the diagonal to yield two half square triangles per square (for sections 5, 8, 11 and 14 on the templates).

Step 2

Cut the white fabric as follows:

  • Eight (8) 2in squares (for section 1 on the templates).
  • Sixteen (16) 1¼in x 2in strips (for sections 3 and 4 on the templates).
  • Sixteen (16) 1¼in x 2½in strips (for sections 6 and 7 on the templates).
  • Sixteen (16) 1¼in x 3in strips (for sections 9 and 10 on the templates).
  • Sixteen (16) 1¼in x 3 ½in strips (for sections 12 and 13 on the templates).
  • Eight (8) 2½in x 5in strips (for section 15 on the templates).
  • Eight (8) 4in x 5in rectangles (for section 16 on the templates).

Piecing the units

Step 3

The snowflake block is made up of four pairs of units. Each is foundation paper pieced, trimmed to size, the papers removed and the block is then assembled as shown in the layout diagram below.

Step 4

Foundation paper piece the eight templates using the fabric strips, rectangles and HSTs for the various sections on the templates as indicated in the cutting list. For the purposes of the main block, ignore the red line and the red numbering of 2a on the templates. These are only used for the piecing of Lynne’s remix quilt block (not featured in this tutorial).

Step 5

First pin one white 2in square to the back of one of the templates making sure it covers the whole of section 1 plus at least ¼in on each side (Fig 1). The wrong side of the fabric should be facing the back of the template.

Step 6

Pin a print fabric 3in square RST with the white square pinning along the seam line between sections 1 and 2 so that, once the seam is sewn and the print fabric is folded over, it will cover section 2 by at least ¼in on each side (Fig 2).

Step 7

Flip the paper template over so the printed side is up and sew along the line between sections 1 and 2 extending the seam approximately ¼in beyond each (Fig 3).

Step 8

Press the print fabric over so it covers section 2 and extends at least ¼in beyond each side (Fig 4).

Step 9

Trim section 2 to ¼in beyond each seam line between section 2 and sections 3 and 4 (Fig 5).

Step 10

Sew 1¼in x 2in strips to cover sections 3 and 4 in the same way. Once sewn and pressed, trim to ¼in beyond the seam line between sections 3 and 4 and section 5 (Fig 6).

Step 11

Continue piecing the templates in the same way until all sections on all eight templates are pieced.

Step 12

Trim the pieced units to size along the dashed lines and remove papers.

Assembling the block

Step 13

Sew the units together in pairs along the diagonals (Fig 7).

Step 14

Sew the pairs of units together to make half of the block (Fig 8).

Step 15

Sew the two halves of the block together (Fig 9). Press the block and check that it is 12½in square.
