2. Hemmed Fabric Insert with a Finished Edge

A step up from the no-sew version, a hemmed fabric insert looks crisp and tailored, especially in woven baskets where the liner is fully visible. The goal is a clean rectangle of fabric that fits inside the bin like a fitted sheet, with neat folded hems on every edge.
You’ll want medium-weight cotton or a cotton-linen blend for this one, since very lightweight fabric can look floppy. Measure the interior of your basket at the top and the bottom, plus the depth. Cut your fabric roughly the size of the bottom measurement plus one inch on each side, and roughly the depth plus two inches for the height. Fold and press a double hem on all four sides, then sew along the folds with a straight stitch. If you don’t sew, fabric glue or iron-on hem tape will work just as well.
Drop the finished piece into the basket. Because the hems are tidy, you can let the fabric rise just slightly above the rim, or trim the height so it sits just below. This style works beautifully for nursery baskets, bathroom storage, and anywhere you want a tailored, intentional look. It’s also reversible: if you use two coordinating fabrics, you can flip the liner to switch patterns on a whim.
Customization is easy. Try contrasting topstitching thread, add a small fabric label, or use a printed cotton that ties into the rest of the room’s color palette.
