Canvass Creases

Just bought a new canvass and its creased where it was shipped to me folded .. how do I get the creases out ?

Canvas or muslin? Canvas should never be folded, it should be rolled on a cardboard tube core. Muslin is designed to be wrinkled. You can steam out the fold marks, but as soon as you fold it or stuff it into its carry bag, it will just wrinkle again.

Poly-Canvas seamless backdrop

This backdrop will be folded and packed in a large box. It may arrive with some wrinkles. but, after you curl it up in a roll, the wrinkle will disappear in a few days. or if you are in a hurry, you can use a warm iron (do not use hot iron) over a piece of wet cotton to flatten the wrinkles. You don't need to have a 100% flat background to achieve a good result.

helps to read the instructions .. sorry
