How to Make a Men’s Flat Cap

How to make a men's flat cap

Finding things to make for the man in your life is often difficult but I came across this free pattern for a men’s flat cap from Waffle patterns and thought to share it with you. I thought this would be a fun project to make for the strong beginner to intermediate sewist. I like that the pattern is free of course but it is the perfect project to make for the man in your life. It comes in two sizes so there is a choice to make. I chose the larger size when making this tutorial but I did change up the instructions a bit.

I headed over to JOANN Fabric & Craft Stores and bought some brushed cotton in a herringbone pattern for my men’s flat cap but you could go to or to get exactly what you want for your project. I used some black Kona cotton that I had in my stash for the lining and some Pellon 809 interfacing to give it some structure.

What you will Need; How to Make a Men’s Flat Cap

Step 1: Cut out your Fabrics

Using the pattern pieces cut the outer and lining upper and outer and lining side on the fold. Cut two brim pieces. Make sure to be cognizant of the grain of your fabric. I wanted my herringbone pattern to be all going in the same direction.

Step 2: Fuse the Interfacing

Fuse the interfacing to the outer upper and outer side of the cap following the manufacturer’s instructions. Cut the Peltex 1/2″ smaller than the brim and fuse it to the wrong side of one of the brim pieces

Step 3: Sew the Back Dart

Fold the outer upper piece right sides together and stitch the back dart using a 1/2″ seam allowance. Press the seam open. Repeat for the lining upper piece as well.

Step 4: Stitch the Side of the Cap

Add the side of the outer cap to the outer upper so that they are right sides together. It may seem like it doesn’t fit but you just need to follow the contours and you will be fine. Stitch using a 1/2″ seam allowance. Press the seam open. Repeat for the lining.

Step 5: Create the Brim

Place the two brim pieces right sides together and stitch around the front curve using a 1/2″ seam allowance. Clip the curves so that it will lay flat. Turn right sides out and press. Topstitch around the front curve of the brim.
