Amazing stuff, iron it on good and proper and it will last wash after wash!
Trick is to use the steam setting on low with fairly even pressure and let it cool down before moving the garement.
Altho I was hemming up jeans by 3 inches I was very sceptical this would work.
So I added the product up the seem of the jeans to both sides of the fold while inside out.
Applied the iron and pressure, trick is to wait 5-10 minutes to let it cool down before moving the material and starting on the other side, never rush the job.
I then applied more of the hem material around the top part of jean fold to secure the loose area. Again I did one side at a time and waited 5-10 minutes for cooling before moving the garment.
Worked a treat without needle or thread and washed several times and has remained firmly intact. Highly recommend this product if you follow the instructions will work a treat.
