I hope you are all enjoying crocheting up your own Carnival Cushion. Today I’m going to show you how to make a round insert to fit your pillow perfectly.

It is so easy to do even with the most basic of sewing skills, it literally took me about 15 minutes!

I’ve just used an old piece of white sheet for my fabric, anything fairly robust will do. Look around in your cupboards, you probably have something suitable laying around.

You can use this technique to make more colourful pillows if you choose fun printed fabrics

You will need:

  • Pillow cover (or final dimensions)
  • Fabric, 2 x pieces larger than your pillow cover
  • Stuffing of your choice
  • Measuring tape
  • Pencil
  • Scissors
  • Sewing machine
  • General sewing supplies

How to:

measure cover finished size

1. Measure your pillow cover diameter, make sure knitted/crocheted covers have been blocked to final shape.

mark diameter on fabric

2. Take your 2 pieces of fabric larger than the cover and fold into quarters. Measuring from the center mark the length of half the diameter plus seam allowance (about 1cm or 1/2 inch). Work around in an arc marking at regular intervals.

I used a 17cm radius for this insert.

3. Your marks should indicate the curve accurately. Without unfolding fabric, cut along marked line.

5. Lay circles on top of each other and sew around edge leaving an opening as indicated in picture above.

6. Stuff insert to desired fullness. Remember contents will settle with use so it’s a good idea to over stuff slightly.

    This is so great! I’ve been wanting to make a cushion insert and my sewing skills aren’t so great but your tutorial has inspired me. Thanks for sharing!

    Thank you for listing “stuffing of your choice” in the materials list. Working for a US government program, I found that polyester fiberfill is listed in the US Toxic Substances Control Act as an inert but toxic fiber, carcinogenic when fibers are inhaled or ingested, and causing endocrine system disruption. It’s nice to see someone not automatically assuming everyone wants to use a poison in their hand-making and is willing to use a traditional stuffing rather than a plastic alternative.
