Sew a Patchwork Throw Pillow From Scraps

Turn leftover fabric into a patchwork throw pillow with this beginner guide to cutting squares, matching seams, quilting the front, and adding a simple envelope back.

Every sewer accumulates a bag of scraps: the leftover strips from a dress, the pretty quarter you bought and never used, the offcuts too nice to throw away. A patchwork throw pillow is the project that finally puts them to work. It turns a jumble of odd fabrics into something deliberate and cosy that lives on your sofa.

It is also a genuinely good teacher. Sewing patchwork trains you to cut accurately and to match seams, two skills that separate wobbly beginner work from projects that look properly made. You get all that practice while making something useful, and you clear out your scrap bag in the process.

Gather scraps and a little kit#

The beauty of this project is that the main material is free, or close to it. Raid your scrap bag for cotton and cotton-blend woven fabrics, the kind that press crisply and do not stretch. Mixing prints and solids gives the liveliest result, but pick a loose theme, whether that is a colour family or a mood, so the finished pillow looks intentional rather than random.

Beyond fabric, the kit is modest:

  • A rotary cutter and self-healing mat, or sharp scissors and patience
  • A clear quilting ruler for measuring straight, square cuts
  • Thread, pins, and an iron
  • A pillow insert, or stuffing, in the size you are aiming for
  • Fabric for the back, which can be one larger scrap or a plain remnant

A rotary cutter and ruler make cutting square, accurate patches so much easier that they are worth borrowing or buying if you plan to do more patchwork. That said, careful scissor work absolutely gets you there too. Wash and press your scraps first, because some fabrics shrink, and a pre-shrunk pillow cover keeps its shape after its first wash.

Cut accurate squares#

Patchwork lives and dies by accurate cutting, so this is the step to slow down for. Decide on a square size that divides neatly into your pillow. For an 18-inch pillow, sixteen squares cut at five inches gives you a four-by-four grid with seam allowance to spare, and it is easy maths to follow.

Cut every square to exactly the same size. Even a small inconsistency multiplies across a grid, and by the time you have sewn four rows together, a sloppy quarter inch here and there leaves your corners refusing to meet. Line your ruler up carefully, hold it firmly, and cut in confident strokes rather than nibbling.

A consistent seam allowance matters as much as consistent cutting. Most patchwork uses a quarter-inch seam, and keeping to it exactly is what makes points and corners line up. If your machine has a quarter-inch foot, use it; if not, mark the quarter-inch line on your machine bed with a strip of tape and follow it every single time.

Lay your cut squares out in the grid before you sew anything, and shuffle them until the arrangement pleases you. Step back and squint at it, or take a photo on your phone, which flattens the colours and shows you clashes you might miss up close. This is the fun part, so enjoy it before the sewing begins.

Piece the front together#

Patchwork comes together in a simple, logical order: sew squares into rows, then sew the rows into a panel. Take the first two squares in your top row, place them right sides together, and sew down one side with your quarter-inch seam. Open them out, add the next square to the row, and continue until the whole row is joined. Repeat for every row.

Press each seam as you go, and here patchwork has a useful trick. Press the seams of row one all in one direction, and the seams of row two in the opposite direction. When you then lay two rows together to join them, those opposing seams nest snugly against each other, which pulls your corners into alignment almost automatically.

Now sew the rows together, one to the next, keeping that quarter-inch seam and matching the nested seams at each junction. Pin right through the seam intersections to hold them aligned while you sew. When you open out the finished panel, the grid should read as clean rows and columns, with corners meeting at neat crossroads. Press the whole front flat.

If you would like extra texture, you can quilt the front at this stage by layering it over a thin piece of wadding and stitching along the seam lines. It is optional, but it gives the pillow a lovely padded depth. The same care with accurate edges pays off in smaller sewing too, like the neat top on a drawstring bag.

Add a simple envelope back#

The back is where beginners often expect a zipper and then avoid the whole project. Skip the zipper entirely and make an envelope back instead, which is easier, needs no special hardware, and lets you slide the insert in and out for washing. It is two overlapping panels rather than one.

Here is the method:

  1. Cut two rectangles for the back, each a bit more than half the width of your finished front, so they will overlap in the middle
  2. Hem one long edge of each rectangle by folding it under twice and stitching, creating the clean edges of the opening
  3. Lay the pillow front right side up, then place both back panels on top, right sides down, with their hemmed edges overlapping in the centre
  4. Pin all the way around and sew the full outer edge, then clip the corners
  5. Turn the whole cover right side out through the envelope opening and push out the corners

Because the two back panels overlap, the opening stays closed on its own when the insert is in, yet opens easily when you need to remove the cover. Give the finished cover a good press, especially the seams and corners.

Stuff it and use it up#

Slide your pillow insert in through the envelope back, working the corners of the insert into the corners of the cover so it fills out squarely. A slightly larger insert than the cover gives a plump, full pillow rather than a saggy one, so if you are between sizes, size the insert up. Plump it into shape and set it on the sofa.

Step back and look at what you made from a bag of leftovers. A patchwork pillow is proof that scraps are raw material, not waste, and once you have made one you will start seeing every offcut as a future patch. Save the trimmings from this very project, because a patchwork habit feeds itself, and the next pillow, quilt, or tote is already waiting in your scrap bag.
