Overview
Fourteen iron-on cotton patches from Zefffka, each 3 by 4 and a quarter inches, meant to cover holes or reinforce weak spots on jeans, jackets and similar cotton garments with just an iron.
Despite where this listing sits in the catalog, it is not a roll of heat transfer film: it is a set of pre-cut fabric patches with a cotton face and a hot-melt adhesive back. Buyers can iron them onto the outside of a garment as a visible patch, or hide them inside a hole so the adhesive backing shows through instead.
- 14 patches, 3 x 4-1/4 inches each
- 100% cotton face, hot-melt adhesive back
- Applies with an iron in about 60 seconds
- Machine washable and dryer safe once applied
Who it's for
Works well for parents patching kids' knees and repeated small tears, and for one-off fixes like a torn jacket seam or a cut blouse. Reviewers who wanted a permanent fix on adult clothing found the patches need reinforcement to last.
What buyers say
From Amazon customer reviews.
Reviewers used these successfully on kids' pants, a safari jacket pocket seam and a cut blouse, with several saying the iron-on bond alone lasted only a few washes before edges started to peel. More than one buyer's fix was to iron the patch on and then stitch around the perimeter for reinforcement, especially on high-friction spots like the crotch or thighs of pants. Color match was called close but not exact in at least one review.
Strengths and trade-offs
Drawn from this product's published specifications.
- Confirmed by reviewers to fix holes and cut fabric fast
- Front is genuine cotton, blends with washed garments over time
- Can be trimmed to shape and applied inside or outside a garment
Performance notes
The front is 100 percent cotton and the back carries a hot-melt adhesive film; pressing with a hot iron for about 60 seconds bonds it to the fabric without sewing. Reviewers who stitched around the patch afterward reported it held up far better under repeated washing and friction than the adhesive alone.

Questions about the Zefffka heat transfer film
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Do Zefffka iron-on patches need sewing?
No, they bond with a hot iron and hot-melt adhesive backing, though several reviewers stitch around the edge for extra hold on high-wear spots.
Can Zefffka patches be applied inside a garment?
Yes, they can go inside so the adhesive backing shows through the hole instead of a visible patch on the outside.
How long do the iron-on patches last after washing?
Reviewers report the adhesive can start peeling after several washes on adult clothing, though re-ironing or adding stitches extends the hold; results on kids' clothing held up well.
