How to Make a Basket Liner | Sew a Custom Fit In An Hour

Sew a basket liner by measuring the basket, cutting separate side and bottom pieces, then sewing them together with a hemmed top edge.

A sewn fabric liner keeps wicker, gift, and storage baskets looking tidy while protecting their contents. The basic method stays the same whether you’re lining a small Easter basket or a bulky laundry hamper: measure, cut, sew, and finish. The trickiest part isn’t the stitching—it’s getting the measurements right so the liner sits smooth instead of bagging or bunching.

This guide walks through the full process with the exact measurement rules, seam allowances, and step-by-step sewing sequence you need. Need a ready-made option instead? Our roundup of the best baskets with built-in liners covers store-bought picks for every room.

What You Need Before You Start

Gather your fabric, sewing machine, thread, scissors, measuring tape, pins, and an iron. Cotton canvas, quilting cotton, and linen work well for most baskets; heavier fabrics hold their shape better in tall or wide baskets. You’ll also need ribbon if you want a tie-on style.

Measure the basket’s inside bottom, inside top, and height from the inside base to the rim. Baskets that taper—wider at the top than the bottom—need angled corners so the liner follows the shape instead of folding over itself. Square and rectangular baskets use four side pieces; round baskets need a single continuous side strip.

How To Measure And Cut The Fabric Pieces

Accurate cutting starts with the right allowances.

• Bottom piece: trace the basket’s inside base, then add 1 inch around the full perimeter.
• Side pieces: cut two short sides and two long sides (for rectangular baskets) at the measured height plus 3 inches, and the top width plus 1 5/8 inches.
• Tapered baskets: measure the top and bottom widths separately. Split the difference in half to determine the corner angle, then draw the angled line on your fabric.
• Seam allowance on templates: if you’re using a paper template traced from the basket, add at least 1/4 inch outside the traced shape before cutting—use 1/2 inch if you prefer a roomier fit.

This extra fabric becomes the cuff that folds over the basket’s rim, so skimping here leaves the liner sliding down inside the basket. When in doubt, cut taller—you can always trim the hem shorter later.

Sewing The Liner Together Step By Step

Prima’s method produces a clean, professional finish in a straightforward sequence. Lay your pieces out before you start so you know which edges join where.

1. Sew the side pieces together. Pin the short sides to the long sides with right sides facing, using a 1/2-inch seam allowance. Sew all four corners to form a loop.
2. Attach the bottom. Pin the bottom piece to the bottom edge of the side loop, right sides together. Sew around the full perimeter, then clip the corners diagonally so the fabric lays flat when turned.
3. Finish the seams. Serge the inner seams or zigzag-stitch the raw edges to prevent fraying. Press all seams open with an iron—this step separates a professional liner from a lumpy one.
4. Hem the top edge. Turn the top edge under 1 inch, then turn it under again (the second fold is also 1 inch), pin, and topstitch close to the inner fold.
5. Fit the liner. Turn the liner right side out, press it again, and drop it into the basket. Fold the cuff over the rim and smooth out any wrinkles. If the liner bunches at the corners, the taper was steeper than estimated—take it out, pin the excess, and re-sew the corner seams.

For a tie-on liner that stays put in baskets with handles, skip the cuff. Create a paper template from the basket’s shape, cut two fabric layers, pin 12-inch ribbons at each corner between the layers, and stitch around the edges leaving one end open. Turn it right side out, press, and sew the opening closed. The ribbons tie around the basket’s rim or handles to hold the liner in place. Prima’s basket liner guide walks through this ribbon method in more detail.

Common Mistakes That Ruin The Fit

Most liner failures trace back to one of four measurement or construction errors. Here’s what goes wrong and how to fix it.

• Too little overhang. The liner slides into the basket and disappears.
• Ignoring the taper. A liner cut straight when the basket widens at the top will bag and wrinkle. Measure top and bottom widths separately and angle the corners.
• Skipping seam allowance. A liner cut exactly to the traced shape comes out too small.
• No corner clipping or pressing. Corners bunch up and seams look lumpy. Clip diagonally at corners and press every seam flat as you go.

These instructions cover sewn fabric liners only—they’re not suited for rigid or waterproof basket inserts. Fit also depends on basket shape; square, rectangular, tapered, and handled baskets each need slightly different piece counts and measurement approaches. No single formula works for every basket, so adapt these rules to your exact dimensions.

Start with a cheap fabric for your first liner if you’re new to sewing baskets. The first attempt teaches you how your specific basket tapers and where the allowances land, and the second liner will fit like it was made in a factory.
