Wonky Wavy Seams

Wonky Wavy Seams Block

Would you like to sew a wonky block with curved seams? It really isn’t as tricky as it looks. These blocks are cut and sewn free form and are SEW easy!


Lay your fabric strips right sides uppermost with a slight overlap.

Wonky Wavy Seam - Step 1

Rotary cut a gentle wavy curve ensuring the cut goes through both layers of fabric

Wonky Wavy Seam - Step 2

Separate the fabrics and discard the small pieces of leftover scraps. (One piece will be on top and the other piece will be underneath)

Wonky Wavy Seam - Step 3

Place fabrics right sides together.

Wonky Wavy Seam - Step 4

You may wish to pin these seams prior to sewing (maybe to gain confidence), but I NEVER bother. If you wish to, then pin as shown.

Wonky Wavy Seam - Step 5

Sew together using a ⅛” seam (4mm). Align seams and sew, stopping periodically and re-aligning fabrics edges together as you sew. If you have the facility on your sewing machine to always stop with the needle position DOWN in the fabric, this makes life even easier as the needle will not drift away from its position each time you stop to re-align.

Wonky Wavy Seam - Step 6 Completed

Press seam in one direction in the usual manner.

Wonky Wavy Seam - Step 7 Completed

You now have a Wonky Wavy Seam!


Continue to cut and sew curved wonky seams, varying the shape of each curve. But, never make these curves too steep or you will have a devil of a time piecing them together.

The block is sewn in the following manner:

Wonky Wavy Block - Stage 1

Wonky Wavy Block - Stage 2

Continue in the same manner with the second round of fabrics.

Wonky Wavy Block - Completed

In this block I have ironed all seams away from the centre.

Wonky Wavy Block - Reverse

Finally when the block is complete, a good press with a steam iron will coax out any small puckers you may have in your seams.

Wonky Wavy Block - Finished

Note: It doesn’t matter that the completed block is not square, because I am going to join it to it’s adjoining blocks with wonky curved seams too!
