Why worn fabric makes the best cushions

Old shirts, school trousers, torn pyjama legs, the offcuts under the sewing table — none of it needs to end up in the bin. A patchwork cushion cover is one of the most forgiving projects in sewing: the fabric is free, the shape is simple, and the more mismatched the pieces, the better it tends to look. Worn cloth also has a softness that new fabric takes years to develop, which is exactly what you want resting against your back.

Aim for a finished cover of 43cm square, which snugly fits a standard 40–42cm cushion pad. That gives you a clear target and stops the project sprawling.

Choosing and preparing your fabric

Not every scrap is worth sewing. Weight matters more than colour here, because a cover built from pieces of wildly different thickness will pull and pucker.

• Middling cottons: shirting, bed linen, dressmaking cotton, light curtain fabric. These are the backbone of a patchwork cover and press beautifully.
• Sturdier pieces: denim, corduroy, canvas, wool trousers. Use these sparingly, a square or two for texture, and trim their seam allowances to 6mm so the joins don't feel lumpy.
• Avoid: jersey and anything with real stretch, which will distort the grid. If you love a stretchy fabric, iron lightweight fusible interfacing onto the back first and treat it like a woven cloth.

Wash and press everything before cutting. Cut around worn knees, ink marks and frayed collars, but keep the best parts of a garment's construction: a shirt placket with its buttons still attached, a jeans pocket, or a neat row of topstitching all make lovely feature squares. Keep the iron moving so you don't scorch prints or melt synthetic blends.

Building a colour palette that holds together

Random scraps often look muddy, but a little planning fixes that. Choose five to seven fabrics and divide them into three roles: one dominant colour (roughly half the squares), two or three supporting tones, and one accent used sparingly.

Then check the contrast. Photograph your squares and switch the image to black and white. If the whole grid reads as flat grey mush, you need more light-and-dark variation rather than more colour. A mix of pale cream, mid-tones and a few really dark squares is what gives patchwork its sparkle. Stripes, checks and small florals are excellent for breaking up large plain squares.

Cutting and laying out your squares

For a 43cm finished front, cut sixteen squares of 11.5cm, plus border strips.

• Cut with a rotary cutter and ruler if you have them, or draw round a card template and cut with sharp scissors. Accuracy now saves unpicking later.
• Sew the squares into a 4 x 4 grid with a 1cm seam allowance. Each square finishes at 9.5cm, so the grid measures 38cm.
• Add a border 4.5cm wide — it finishes at 2.5cm — around all four sides, bringing you to 43cm.
• Lay the front out on the floor before sewing a single seam and shuffle until the colour is spread evenly. Photograph it; that's the fastest way to spot a clump of dark squares in one corner.

Sewing seams that lie flat and look sharp

Neat patchwork is about consistency, not speed. Set your machine's needle position so the 1cm seam allowance is easy to follow, or mark it with a strip of masking tape on the bed of the machine.

• Sew squares into rows first, then join rows to each other. Press seams in alternating directions as you go, odd rows one way and even rows the other, so they nest when joined.
• Where four seams meet, pin through the intersection and check the seams butt against each other before sewing. If they don't nest, unpick a short section rather than forcing it.
• Don't pull the fabric through; let the feed dogs do the work. Pulling stretches the seam and creates a wavy edge no amount of pressing will fix.
• Press, don't iron. Set the seam with a hot iron, then open it with the tip, using a pressing cloth on dark or delicate fabric. Trim stray threads and grade bulky seams as you go.

Finishing the cover: envelope back and final press

An envelope back needs no zip and no buttonholes. Cut two rectangles from a sturdy fabric, about 43cm x 30cm and 43cm x 25cm, so they overlap by roughly 12cm in the middle. Hem one long edge of each with a double fold, 1cm then 1cm again, and stitch close to the fold.

Place the front panel right side up, lay the larger back piece on top right side down with its hemmed edge across the middle, then the smaller one over it with its hemmed edge facing the opposite way. Pin, sew all the way round with a 1cm seam, and clip the corners diagonally before turning the cover right way out. Press the edges firmly, push a pad inside, and stand back. One worn-out shirt, one old pair of jeans and a quiet afternoon at the machine, and you have a cushion that looks deliberately designed rather than merely saved.
