Going Bigger?

If you want to make this quilt larger, keep an even number of rows, with an odd number of shapes in each row. It will make the top and bottom, and each side of the quilt symmetrical.

Cutting Instructions:

Fabric scraps: Cut the scraps 3/8" larger on all sides than the Crown and Kite paper templates.
Solid: Cut (7) 2" x width-of-fabric strips. Using the Diamond and Triangle paper templates as a guide, cut 104 Diamonds and 20 Triangles, leaving a 3/8" seam allowance on all sides.

English Paper Piecing Basics:

Paper pieces are accurately cut into the various shapes needed for the quilt construction. Each piece is a "block" of the finished design. To work with the paper template, the cut fabric pieces should have a 3/8" seam allowance on all sides of the shape.

If thread basting, centre the paper template on the wrong side of the fabric, fold over the seam allowance on one side and clip in place to hold it. Fold the adjacent side fabric over the template and stitch 3 small stitches in the corner to hold the folds together. The stitches should go through only the fabric, not the paper, as it will be removed once the quilt is completed.
Continue folding the adjacent sides over the paper and stitching in the corner to hold the fold in place.

If glue basting, centre the paper template on the wrong side of the fabric and glue lightly along one side. Fold over the seam allowance over that edge and finger-press. Glue along the adjacent side, fold seam allowance over and press. Continue gluing the adjacent sides of the template and finger-pressing the seam allowances down.

Repeat this process for each piece in the quilt.

To join pieces, place two adjacent pieces right sides together and whipstitch the fabric folds together with tiny stitches (only through the fabrics, not the papers). Instead of tying knots, use 3 small stitches in each corner to secure the pieces.
When the thread becomes too short, simple sew 3 stitches to anchor, then begin with a new thread length and 3 more stitches to secure it.

Stitching the quilt top:

1. Prepare all the pieces for the quilt by basting the fabric to the paper templates. The solid colour fabric is used for all the Diamonds and the Triangles, and the assorted scraps are used for all the Crowns and Kites.

2. Lay out the quilt in rows to create a pleasing arrangement of colours. The featured quilt has 12 rows of 17 Crowns each, with a Kite at each end and solid colour Diamonds in the spaces between the Crowns.

3. Once you have a pleasing arrangement, number the rows for easier assembly. It's easy to mark on the paper template the row number and location, or simply stack the pieces from each row in order for stitching.

4. Row 1 begins with a Kite, with the point to the top left corner of the quilt. Join it to a Crown (pointing down). Keep the thread attached to the pieces after securing the stitching line so you can sew continuously to add the next piece. Open out the pieces.


5. Add the next Crown, pointing up and continue joining the pieces. After you have 17 Crowns, finish the row by adding a Kite, pointing to the top right.










6. To fill in the gaps in the top of the row, add 10 solid Triangles (3).





7. To fill in the gaps between the Crowns, add 9 solid Diamonds (4).

8. Continue stitching all the rows, adding Diamonds to fill in the Crown gaps and Kites at the row ends. Note that the even and odd number rows mirror each other, and differ in the number of Diamonds needed. For row 12, add Triangles to fill in the bottom gaps.







Assembling the Quilt

9. Join the rows in numerical order. Place row 2 over row 1, right sides together. Using 3 stitches for anchoring the threads and small whipstitches for joining the fabric folds, sew the edges of the pieces together, bending the papers as needed to match the edges and corners.

10. Add the rows one at a time, and remove the papers, if desired, once a row is completely surrounded. Doing so as you go makes the quilt a bit lighter to handle for sewing subsequent rows, but you can wait until the quilt is completed before removing papers if desired.

11. Once the quilt is complete, remove any remaining papers and press the quilt top flat.


12. Open out the turn-under of the outside edge pieces and press again.

13. Layer the backing (wrong side up), batting, and quilt top (right side up). Baste the layers together.  Quilt as desired. The featured quilt was hand quilted with perle cotton using vertical lines between the diamond points and outlining around the diamonds.

14. Trim the excess quilt top, batting, and backing 1/4” beyond the seam line where the papers have been.

15. Sew the binding strips together end to end using diagonal seams. Press the binding in half wrong sides together.

16. Leaving an 8" tail of binding, sew the binding to the quilt through all layers, matching all raw edges. Miter corners. Stop approximately 12" from where you started. Lay both loose ends of binding flat along quilt edge. Where these two loose ends meet, fold them back on themselves and press to form a crease. Using this crease as your stitching line, sew the two open ends of the binding together right sides together. Trim seam to 1/4" and press open. Finish sewing binding to quilt.

17. Turn the binding to the back of quilt and hand-stitch in place.
