How to Make a Flannel Blanket: A Cozy DIY Guide

How to Make a Flannel Blanket: A Cozy DIY Guide

Flannel blankets are a staple in any cozy home, known for their softness and warmth. Making your own flannel blanket can be a rewarding project, whether you’re crafting a personal gift or just looking to enhance your bedding ensemble. This guide will take you through the steps to create both single-layer and double-sided flannel blankets.

How to Make a Flannel Blanket

Creating a single-layer flannel blanket is a straightforward process that’s perfect for beginners looking to craft something useful and warm. Here’s a detailed guide to help you through each step:

Materials Needed

Step-by-Step Instructions

  1. Prepare the Fabric:

    • Wash and dry your flannel fabric to pre-shrink it. This step prevents distortion after your blanket is complete.
    • Iron the fabric to remove any wrinkles, ensuring a smooth working surface.
  2. Measure and Cut:

    • Lay the fabric flat on a large surface.
    • Use the measuring tape to measure your desired dimensions.
    • Mark your measurements with chalk or a fabric marker.
    • Cut the fabric using scissors or a rotary cutter for precision.
  3. Hem the Edges:

    • Fold each edge of the fabric over by about half an inch (or more if you prefer a wider hem). This fold will create the hem.
    • Pin the fold in place to prepare for sewing.
    • Sew the hem using a straight stitch along the edge of the fold. Be sure to remove the pins as you sew.
  4. Adding Decorative Touches (Optional):

    • Sew ribbons or fabric strips along the hem for a decorative edge.
    • Consider adding a personalized label or embroidery before hemming if the blanket is a gift.

Pairing your homemade flannel blanket with a Puffy Lux Mattress can transform your sleep experience, as the softness of the blanket complements the mattress’s supportive comfort.

How to Make a Double-Sided Flannel Blanket

Double-sided flannel blankets provide extra warmth and comfort by combining two layers of fabric. They also offer an opportunity to mix and match colors and patterns.



  1. Prepare the Fabric:

    • Pre-wash and iron both pieces of flannel as described in the single-layer blanket instructions.
  2. Cut the Fabric:

    • Ensure both pieces are cut to the exact same dimensions for a neat finish.
  3. Pin the Fabric:

    • Lay one piece of fabric on a flat surface with the right side facing up.
    • Place the second piece of fabric on top, right side facing down so the right sides of both fabrics are together.
    • Pin around the edges to secure the two pieces.
  4. Sewing the Blanket:

    • Sew around the edge of the blanket, leaving about a 5-inch gap unsewn. This gap will be used to turn the blanket right-side out.
    • Use a half-inch seam allowance for durability.
  5. Turn the Blanket Right-Side Out:

    • Carefully turn the blanket right-side out through the unsewn gap, ensuring the corners are fully extended.
    • Iron the edges to make them crisp and flat.
  6. Close the Gap:

    • Pin the opening closed, folding the raw edges inward.
    • Topstitch around the entire perimeter of the blanket, about a quarter-inch from the edge. This not only closes the gap but also adds a finished look and additional durability.
  7. Final Touches:

    • For added decor, you can sew a decorative border or apply fabric appliquĂ©s.

I remember the first flannel blanket I made—it was for my son’s first winter. Choosing the fabric, cutting, and sewing it together while imagining him snuggled up in it was incredibly fulfilling.

Over the years, making these blankets has become a cherished activity for our family, providing not just warmth but also a sense of comfort knowing each piece is made with love.


Making a flannel blanket is a fun, practical project that can be tailored to suit any style or need. With the right materials and a bit of time, you can create a beautiful, durable blanket that’s perfect for any occasion—from a chilly winter night to a cozy addition to a mattress. Start your project today and wrap yourself in the comfort of your own creation!
