The book instructions for foundation paper piecing use an inset seam which is easy to omit. I didn't use the original pattern and instead I printed out the block diagram (if printed at 100% it should come out at 6" square) and redrew and labelled the different sections. The example below is an illustration and is not to scale. Instead print the block diagram from the CD and add the lines and labels as below.
Cut along the blue lines that mark the different sections A, B C, D and E. You can add ¼" seam allowances around the outer edges of sections A, B, C, and E but these will have to be allowed for on the other edges when you add the fabric pieces.
Precut the fabric pieces using the measurements below, I've included my colour choices for clarity but substitute with your own. These are not precise, instead they will give you the larger seam allowances that provide the necessary wiggle room in paper piecing!
Rotary Cutting for Foundation Paper Piecing
B4, C4: Cut (2) 1 ¾" x 5 ¼" rectangles
A3: Cut (1) 3" square and sub-cut in half across the diagonal to make 2 half square triangles. You will need 1 of these.
B2, D2, C1: Cut (3) 1 ¾" squares in yellow
B1, C2: Cut (2) 1 ¾" squares in green
C3, D1, D3: Cut (2) 2 ½" squares and sub-cut in half across the diagonal to make 4 half square triangles. You will need 3 of these.
A2: Cut (1) 2 ½" squares and sub-cut in half across the diagonal to make 2 half square triangles. You will need 1 of these.
Top tips for this block
- Pre-cut all pieces
- Use a water based glue stick. I use Sewline, to stick the first piece of each section
- Chain piece- the four sections are identical
- Nest seams where possible to match seam points
I sewed up sections A, B, C and D adding on the extra ¼" seam allowances where needed. My labelling is slightly different from the block diagram, I changed it a little for the diagram to create better seam nesting for you!
Join A to B and press seam open. Join C to D, pressing seam open. Join AB to CD pressing seam open.
Use the completed ABCD triangle as a template to cut piece E. Place it right sides together on top of fabric for E and cut out with a rotary cutter. Whilst the two sides are still together, pin along the diagonal and stitch the joining seam. Press towards E. Carefully remove paper, starch if desired and press.
