Dress up plain paper gift bags with fabric scraps
A narrow strip of leftover fabric can give a plain bag a finished look while keeping the bag easy to reuse.

Open the paper bag fully and look at the base, side folds and handle attachments. Creased paper is usually harmless, but a split seam or loose handle makes the bag unreliable. Test it with the actual gift while holding the base. If the present is heavy or has a sharp edge, use a sound box or stronger packaging rather than hoping a ribbon will reinforce thin paper.
Remove an old name tag if it comes away cleanly. Leave a stubborn label in place and cover it with a new card instead of tearing the surface. A plain patch of paper can become part of the design. There is no need to make a reused bag look as though it has never been used.
Let the fabric's edge guide the treatment
A soft cotton scrap can be cut into a strip and tied around one handle, while a sturdy woven offcut may work as a small rectangular tag. Check for loose threads that could tangle around the gift. Trim them neatly; an intentionally raw edge can look good without leaving long strands hanging.
For a simple bow, make two loops and leave enough length to untie it later. Avoid tying both handles together so tightly that the recipient must cut them to open the bag. If the fabric is bulky, use a single knot or attach a folded strip to the tag instead. The accent should not make the handles uncomfortable to carry.
Tie the decoration on where possible. Permanent glue can stiffen the bag, leave marks and complicate reuse. A removable tag gives room for the recipient's name and a short message without writing across the paper itself. Use a contrasting card if the fabric has a busy print so the name remains easy to read.
Choose the fabric around the gift's size, not the other way around. A broad bow on a tiny bag can cover the opening and make the package awkward. On a large bag, one small patterned strip may provide enough color when the rest is plain. Repeat a color in the card if you want the pieces to relate; matching every element is unnecessary.
After the gift is opened, the strip can be saved with wrapping supplies and the bag folded along its existing creases. If you are preparing several bags, keep the decorations separate until they are needed so the bows are not crushed in storage. Small scraps are useful here precisely because they do not need to become another finished craft project waiting for a place to live.
