How to Sew a Simple Tote Bag from Fabric Scraps
Turn leftover fabric into a lined, sturdy tote bag with reinforced handles — a beginner-friendly sewing...
There's a moment in a pair of jeans' life when the knees go, the hems fray and the fabric turns soft and pale — but the denim itself is still stubbornly tough. That cloth has already survived years of wear, and it will happily survive another decade on a sofa. Cutting it into patchwork is one of the best uses for it: the finished cover shrugs off muddy paws, spilled tea and general family life far better than any lightweight cotton.
You don't need much to make one. A 4×4 grid of squares, a back closure and a bit of patience at the ironing board will give you a 45cm cushion cover in an afternoon. This is a good second or third project for anyone who can sew a reasonably straight line. The beauty of patchwork denim is that it never looks mass-produced. Every fade, seam and worn edge becomes part of the design, so small mistakes disappear into the texture rather than shouting for attention.
Not every worn pair is worth unpicking. Look for jeans that are still sturdy across the seat and thighs, where the fabric has worn thin only at the knees or hems — those areas can be trimmed away and discarded, leaving you with large, strong panels. Avoid jeans with thin, papery patches across the seat, split back pockets or stretch denim that has lost its shape; those sections will sag or tear under the stress of a cushion. If a pair is too far gone, salvage the back yokes, waistband and pocket bags — they can become pockets, tabs or contrast patches on your cover.
Wash and dry your jeans before cutting, especially if they come from a charity shop or a dusty loft. Denim shrinks, and you want that shrinking to happen before you sew, not after. Once clean, lay the jeans flat and cut along the outside leg seams to open each leg into a flat panel. Remove the thick inner seams, hems and any bulky hardware. You are aiming for clean, flat pieces of cloth that will press nicely and feed under the machine without wobbling.
A 4×4 grid is forgiving. It gives you sixteen squares, which is enough to create a balanced mix without becoming a puzzle. For a 45cm finished cover, each square should finish at about 11.25cm. Add a 1cm seam allowance on all sides, and you will cut squares of roughly 13.25cm. If you prefer a slightly larger cushion, say 50cm, use 12.5cm finished squares and cut 14.5cm squares. Write your measurements down before you cut, because denim has a way of making confident guesses feel foolish later.
Use a consistent seam allowance throughout, ideally 1cm. Denim frays, and a generous seam allowance gives you security. If you are using very thick denim, you may prefer to press seams open rather than to one side, which reduces bulk at the intersections. Just be aware that open seams can be weaker, so backstitch at the beginning and end of every row.
Spread your squares on a table and arrange them before sewing. Try alternating light and dark washes, or group similar shades in diagonal lines. Include one or two squares with a back pocket, a faded whisker mark or a visible seam for character. If everything looks too uniform, add a square cut from a different pair. If it looks too chaotic, remove the loudest piece and replace it with a calm mid-blue.
Join the squares into rows first, then join the rows together. Place two squares right sides together, pin along one edge, and sew with a 1cm seam allowance. Backstitch at both ends. Continue until you have four rows of four squares. Press each row flat, pressing seams in alternating directions. This nesting makes the next stage easier: when you sew row one to row two, the seams will butt against each other instead of creating a lump.
Next, pin and sew the rows together. Match the intersections carefully. It helps to pin at each seam line first, then fill in the gaps with more pins. Once the front panel is complete, give it a final press. It should measure approximately 45cm square, though a little variation is normal and charming.
Patchwork is not about perfection. It is about giving good cloth a second life, and every slightly crooked seam is proof that a human being made it.
You have several choices for the back. The simplest is an envelope closure, which requires no buttons, zipper or extra hardware. Cut two rectangles from denim. Each should be as wide as the front panel and about two-thirds as tall. Hem one long edge on each rectangle by folding it over twice and stitching. Overlap the two hemmed edges in the centre of the back, then pin them to the front panel. The overlap should be at least 10cm so the cushion pad cannot escape.
For a more traditional look, cut one large back panel and one narrower flap. Hem the flap, then add buttonholes and sew buttons to the main back panel. This takes longer but looks handsome, especially if you use old metal jeans buttons or mismatched wooden ones.
If you are confident with a zipper foot, install a 40cm zipper in the centre of the back panel. Denim hides zipper imperfections well, but the zipper itself can be bulky. Use a lightweight zipper and press carefully around it.
Once you have made one cover, the format is easy to adapt. Use a 5×5 grid for a smaller, more intricate cushion. Add a pocket to the front for remote controls or reading glasses. Appliqué a heart or star cut from red denim onto a plain square. Make a matching set using the same sixteen squares in different arrangements. You can also sew a simple quilted panel behind the patchwork for extra softness, though denim alone is usually sturdy enough.
Turn the cover inside out and wash it on a cool, gentle cycle with similar colours. Avoid bleach and harsh detergents, which will fade the denim unevenly. Tumble dry on low or air dry flat. If the cover wrinkles, press it with a medium-hot iron while slightly damp. Denim will soften with every wash, so the cushion will only become more comfortable with age.
Making a patchwork cushion cover from old jeans is a small act of rebellion against throwaway culture. It costs almost nothing, keeps good fabric out of landfill and produces something genuinely useful. Best of all, every time someone asks where you bought it, you get to say you made it from a pair of jeans that had already lived a full life.
