How to Sew a Sailor Hat

Updated February 21, 2017

A sailor’s hat is a cute addition to a sailor costume or a quirky accessory for a fun outfit. If you want create this style hat, you can easily make one to coordinate with whatever clothing you wear. You can even decorate it, making it a truly personal piece of fashion.

Draw a rectangle that is 4 inches wide and 5 inches tall on a piece of paper with a pencil. The sizes given are for a small adult. To change the size of the hat increase or reduce all of the measurements proportionally according to the steps.

Round off the top corners to make the rectangle into a triangle with a wide lower body, like an arched window. You can start to curve the sides at 2 inches down from the edge of the rectangle.

Cut out the shape on the paper with scissors and trace it onto the fabric four times. Cut out all four of the traced fabric shapes.

Place two of the shapes on top of each other, with the right sides facing each other. Do the same for the other two pieces.

Sew the pieces together along one of the vertical edges with your sewing machine set on a straight stitch. Do this for both sets of two pieces of material.

Open up one set of the pieces and place it flat on a table, with the seam side down. Place the other set on top of the first one, with the seams facing up. This is the crown of the hat. Sew the two sets of pieces together along the open vertical edges.

Cut another piece of fabric that is 15 inches long and 5 inches wide and fold down the top, bottom and left side edges of the fabric. The folds should ¼ inch wide.

Fold the fabric in half so it is 2 1/4 inch wide. All of the folded raw edges should be inside the fold so you don’t see the edges.

Slip the fabric over the edge of the crown part of the hat. The seams of the crown should be facing out and the fabrics should overlap by 1/4 inch.

Insert the end of a 1 1/2-foot-long piece of ribbon in between the folded fabric and the crown fabric. You should insert another piece in the same way, immediately opposite from the first one. These are the straps to hold the hat in place.

Sew the folded fabric and the crown together along the section where they are overlapped. Make sure the ribbons get stitched too.

Push the crown so the seams are inside rather than out. The edge of the brim should be upwards and the ribbons should be hanging down.


For an authentic looking hat, use navy and white colours for the fabric.
