CELTIC TWIST Quilt Block | Step-by-Step Tutorial

This tutorial is for the 17" x 17" Celtic twist block shown above. It may look complicated, but it's simple to put together. There are no Y-seams and no templates to worry about. The block consists of two 6 inch units (one is a snowball block) and two different sized triangle units; that's it! You can make one block or add more units to make a quilt or table runner. I love this block for showcasing big prints.

These are the four units to make the block.

(All measurements include a 1/4 inch seam allowance)

Unit 1 - Makes 4
[8] 5" x 2" dark print
[8] 5" x 2" light print
[4] 3½" x 3½" medium print

Unit 2 - Makes 4
[1] 7¼" solid

Unit 3 - Makes 4
[2] 7" solid
[4] 2" x 2" dark print

Unit 4 - Makes 1
[1] 6½" x 6½" large print
[4] 2" x 2" light print

UNIT 1 - Make 4

1. Arrange your fabric pieces to ensure you have the correct colour placement. You'll need [2] 5" x 2" dark print; [2] 5" x 2" light print; and [1] 3½" square medium print to make one 6" block.

2. Place the square and first piece right sides facing and start stitching 1 inch from the top of the square.

3. Flip and press the first piece. Place the next piece right sides facing and stitch to end.

4. Flip and press the last piece you stitched. Place the next piece right sides facing and stitch to end.

5. Flip and press the last stitch pieced. Pull back and pine the first piece sewn on and pin back. Place the last piece right sides facing and stitch to end. Flip back and press.

6. Fold back the first piece as shown and stitch to just past the starting point of your first stitches.

7. Press completed block.

UNIT 2 (One square makes four triangles)

1. Cut [1] 7¼ solid colour square.
2. Cut the square diagonally to each corner to make four triangles.

UNIT 3 - Make 4

1. Pin one [1] 2" dark print square with right sides facing on opposite corners of the 7" solid colour square and stitch as shown. Cut a 1/4 inch seam allowance from each corner square, flip and press back.

2. Cut from corner to corner parallel to stitched corners to make two triangles.

UNIT 4 - Make 1

1. Cut [1] 6½ inch large print square and [4] 2" light print squares. Pin one 2" square with right sides facing on each corner of the larger square as shown.

2. Cut a corner inch seam allowance from each corner square, flip back, and press.

  2. Can you tell me how many blocks I would need to make a queen size quilt?

    1. This depends on the size of the block and the size of your quilt. Here is a good link to help you out. http://delawarequilts.com/MyQuilts/Sizes.html
