How to make a quilt binding using bias tape

A quilt binding frames the front and protects the raw edges of the batting and backing. Bias tape suits this job because its diagonal cut gives enough give to follow curves without buckling. Buy it ready folded or make a continuous strip from quilting cotton.

Australian quilters often use cotton scraps from Op Shops or the offcut bin for borders and labels. In Brisbane’s summers, lightweight cotton may suit a bed quilt; in Melbourne, a stronger cotton blend can work for a winter throw.

Single-fold binding shows one side of the tape; double-fold binding gives a wider, enclosed finish. Match the width to the quilt thickness and backing allowance. Trim and press the quilt, join the tape into one strip, sew it to the front, mitre the corners, and fold it to the back.

Many sewists in Sydney, Melbourne and Adelaide sew indoors during hot weather. Australian quilt markets let buyers compare cotton binding in person. Good light and a pressing cloth matter more than specialist tools.

Choose the right bias tape

Single-fold tape has one crease; double-fold gives a neater enclosed edge. Homemade binding can be cut to suit the quilt, while pre-made tape saves time and keeps the width consistent. Check grain and stretch, especially with linen.

For a domestic quilt, 2.5 cm (1 inch) folded binding suits a thin or medium quilt, while 3.8 cm (1½ inch) suits a thicker sandwich. Measure the exposed edge. Diagonal stretch helps the tape curve, but stretchy fabric can make corners grow.

Pre-made binding is sold by the metre in Australian fabric shops or online. Leftover quilting cotton in complementary colours can make a continuous border. Wash new fabric first, since shrinkage affects length.

Choosing the right tape involves several considerations. Choose single-fold or double-fold tape depending on the required finish. It is necessary to match the width to the thickness and allowance of the quilt. Selecting stable cotton ensures easy pressing. Use diagonal tape specifically for creating curves. Finally, buy enough to cover the perimeter and overlap.

Prepare the quilt edge and make the tape

Press the quilt top, then trim the batting and backing so the layers are even. Leave a consistent allowance, clip curves, and square the corners. An undersized backing can pucker; an oversized one makes a lumpy hem. Remove pins and use a rotary cutter and ruler.

To make bias tape, cut strips at 45 degrees to the straight grain. Join short ends right sides together, press the seams open, and trim the allowance. Continue until the strip can encircle the quilt with extra for the corners. Multiply the perimeter by about 1.4, adding more for a bulky quilt; bought tape should exceed the perimeter.

Before sewing, confirm that the machine makes a straight stitch and the needle suits cotton. For a first-time setup, this sewing machine setup reference helps check the foot, stitch length, and clearance. Keep a spare needle and fabric scrap nearby.

Essential tools prepare the binding process. A quilting ruler is necessary for trimming and checking the allowance. You will also need a rotary cutter and mat, or sharp shears. Cotton thread should match the binding. Fabric clips are useful for holding folded corners. Finally, prepare an iron, pressing cloth, and test fabric.

Join one continuous binding strip

Join homemade strips at right angles, matching grain, and sew the diagonal seam. Press every seam consistently; mixed directions can make the tape twist. Trim the allowances so the strip lies flat, then form a ring, leaving loose tape at the ends to tuck.

Press the strip. A walking foot or light hand tension helps layers advance evenly. Test around a scrap edge: the tape should hug a curve without stretching the quilt or leaving a ridge. Local binding is labelled by tape width rather than finished allowance, so read the packet carefully.

At an Australian quilt market, sew a test strip from each fabric. Cotton, linen blends, and printed cottons can behave differently even when they look similar. This check prevents a large batch from shrinking or twisting later.

Attach the binding and mitre the corners

Place the quilt right side up. For double-fold tape, fold it in half lengthwise and match its raw edges with the quilt edge; for single-fold tape, align both raw edges directly. Sew 5–7 mm (¼ inch) from the edge, keeping the tape flat with slight ease. Stop before sewing across a corner if you will form the mitre by hand.

At each corner, align the tape with the quilt corner. Fold it diagonally so the crease runs towards the next side, creating a 45-degree mitre. Open it, align the long edge with the next side, and continue. Press the mitre; a flat corner is easier than a tight one. When the ends overlap, sew the join and check that the mitres meet squarely.

Fold to the back and secure the ends

Turn the binding onto the quilt back. With double-fold tape, the enclosed fold hides the raw edge; with single-fold tape, fold the raw edge over the back. Fold each mitre into an envelope, trim excess, and clip it. Sew through the binding and backing with a short straight stitch. A walking foot keeps the layers flat.

At the starting and ending ends, fold raw tape edges inward and stitch them down. Keep corners square, but do not pull so tightly that the binding ripples the quilt top. Press both sides, checking that no backing is caught in the front seam and that the batting stays within the binding.

Sew a label onto the backing before attaching the binding so it is hidden neatly. For a puffy quilt, inspect the corners after the final press; small gaps are easier to fix before storage.

Check the finish and care for the quilt

Spread the quilt on a table and examine the binding in good light. Look for flat mitres, even stitching, loose ends, and twisting. A border that lies flat when laid out will usually stay flat when rolled or displayed. Adjust puckering before adding more stitches.

Care for the quilt according to the fabrics used, not just the tape. Cotton binding can usually be washed gently with the quilt, while linen or specialty trim may need another method. In humid weather, store it in a breathable cotton bag and air it regularly. Avoid leaving it in a hot car boot when transporting a quilt to a show.

When buying a sewing machine from an Australian supplier, keep the receipt and check the warranty. The Australian Consumer Law provides consumer guarantees for goods supplied in Australia, including protection against faulty products, so a retailer cannot ignore a legitimate claim. Remedies depend on the circumstances, but clear records help. Follow the safety instructions supplied with an electrical machine, not an overseas manual.

Melbourne, Sydney and Brisbane quilt guilds often share pressing tips. Give the quilt a final press and check that it lies flat.
