Waterfall Edges, Twill Tape, and Backing for Tufted Rugs
A folded edge hides the raw primary cloth. Twill tape can cover the join on a straight rug, while the backing should suit where the rug will be used.

Choose the edge finish for the rug
Start by folding the loose primary cloth over the edge. Add twill tape when you want to cover the join, then choose a backing for a floor rug or wall hanging.
| Rug use | Edge and backing | When tape helps |
|---|---|---|
| Curved or irregular shape | Fold the spare cloth to the back and make relief cuts in the loose margin so it can lie flat. | Tape can be awkward around changing curves. Try a small section before using it around the whole edge. |
| Rectangular floor rug | Fold the edge, then choose non-slip backing labeled for floor use. Follow the backing and adhesive makers’ instructions before combining them. | Use tape across the join if you want to cover the seam between the folded cloth and backing. |
| Wall hanging | Fold and cover the edge with a light backing or fabric that suits the hanging method. | Grip backing is unnecessary when the piece will not sit on a floor. |

Fold the cloth without cutting into the pile
- Leave enough loose primary cloth to turn over the rug edge. Keep the cut away from the stitched yarn.
- On outside curves, make small relief cuts in the loose margin so it can spread. At inside corners, use short slits so the cloth can fold without bunching.
- Work on the back of the rug. Apply the glue to the cloth fold, press it down in short sections, and check the front as you go.
- Before attaching the full backing, test the adhesive and backing together on an offcut. Follow the instructions for the exact glue stick and surfaces.
Keep hot glue away from exposed yarn on the side wall. A suitable roller or pressing tool can hold the fold while the adhesive sets.
Place twill tape over the seam
Fold and secure the primary cloth first. Fit and trim the secondary backing next, then place cotton twill tape across the meeting seam if it needs a cover. On a rug with tight curves, check that the tape lies flat before gluing it all the way around.
For the earlier adhesive and backing choices, see the backing system guide and the adhesive guide.
Use hot glue only when the stick instructions allow it
A general-purpose glue gun is not a documented rug-backing adhesive. Follow the glue stick’s instructions for the cloth and backing you are joining, and try the combination on an offcut before you glue the rug.
Keep the glue on the back of the fold, away from exposed yarn. Press the fold in short sections and check the front as you go.

Common questions
How do I finish a curved tufted rug edge?
Fold the loose primary cloth to the back. Make relief cuts in the spare cloth where needed so the margin can lie flat around curves, and keep every cut clear of the stitched yarn. Secure the fold in short sections and check the front as you work.
Should twill tape go over or under the rug backing?
Fold and secure the primary cloth edge first. Fit the secondary backing against the fold, then place twill tape over the join if you want to cover that seam.
How do I keep hot glue off the front yarn?
Apply glue to the back of the cloth fold, away from exposed pile. Test the glue stick and backing on an offcut first, then press the fold with a suitable tool while following the glue manufacturer’s safety instructions.
