Beginners 16″ Octagonal Nine Patch Cushion Cover

This is a pretty quick and easy project. You’d be able to get this done in an hour or two, which makes it so gratifying and fun! It’s also a great platform to start and see if patchwork is for you. Let’s begin!

A) Background fabric B) Front fabric

For material, you will need 5 fat quarters (18″ x 22″) and 18″ square batting:

  • 2 fat quarters for patchwork (front and background)
  • 1 fat quarter for the backing for the quilt sandwich (this will be inside of the cover, so you wouldn’t need anything fancy)
  • 2 fat quarter for the cushion envelope
  • 1 square of batting measuring 18″ x 18″
Cut “Square 1” diagonally to make triangles.

Cutting for patchwork:

  1. Square 1 (cut into squares and then cut diagonally in half to form triangles):
    1. 2 square cuts of front fabric
    2. 2 square cuts of background fabric
  2. Square 2:
    1. 4 square cuts of front fabric
    2. 1 square cut of background fabric
  3. Cushion envelope (these are to overlap for the back of the cushion to form an envelope):
    1. 1 cut of 11″x 18″
    2. 1 cut of 13.5″ x 18″
  4. Batting (my preference is always either cotton or bamboo):
    1. 1 square cut of 18″ x 18″


Change your machine foot to a 1/4 inch foot. Start by piecing the triangles. Pair a front fabric and a background fabric, right sides together and pin along the diagonal line. Then start sewing a 1/4 inch seam along the diagonal part of the triangle.
Bring the sewn pieces to the ironing board and press it towards the dark (darker fabric).
Square the pieces. You want to trim away the pointy ends and square them up so it’s easier to piece the whole thing together. Using the block pattern above as a guide, lay out your squares to create the octagonal shape.
Stitch these together in blocks of three. Bring these back to the ironing board and press the first and third row in one direction and the second in the opposite direction. This will allow the seams to nest nicely when you piece them together.
Once again, bring it to the ironing board, press and square the block. Tada! Patchwork part is complete! You are half way to having your very own handmade cushion cover my friend!
Now we want to create a “sandwich” for the quilting portion. Smooth out the backing fabric, right side facing down, and spray it with some basting spray. Place the batting on top, smooth it out and spray more basting spray and place the patchwork on top of it. Smooth it out.
I use basting sprays instead of pins because it is just so much easier! If it was a super large quilt, I would probably bast it with spray and put a few pins around to help with the weight. Quilt Basting sprays won’t harm your machine or your quilt. It’s washable. Just use it as per the instruction. Use, don’t abuse 🙂
Bust out the masking tape. Use the masking tape to mark the quilting lines. Screw on the walking foot and start the quilting process by sewing close to masking tape. These work as guides, I ended up sewing more lines than these to make sure that my batting sits nicely in this quilt sandwich. Once again, square off the excess material. There you have it! Your first quilt sandwich!!
For the cushion envelope, hem one side of each piece. Fold the length of the fabric and once again onto itself. Press it well with the iron.
Sew the hems shut. I do it twice, once on the top and another on the bottom to make sure it wouldn’t stray.
Now this is the finisher! Bring back the quilt sandwich, right side up. Align the envelope pieces at the top and bottom of the quilt sandwich, right side down. These will overlap. I placed the wider piece on top of the shorter piece. Pin them down. Sew the edges together with a 3/8″ seam. Trim off excess material.
Trim off the edges of square and flip it inside out. Stuff it with a cushion and you are done! Since this is a 16″ cushion cover, you can stuff it with a 16″ cushion inner, unless you prefer a puffier looking cushion, in which case you can place in a 17″ inner.
Your first completed patchwork/quilting project! High fives all around!

I would love to hear from you and see the projects that you have done. I hope you’ve found this tutorial helpful and perhaps found a new love in quilting!
