Fabric painting helps in a better way to change your home and any other room especially your wardrobe.
An important thing to keep in mind is that a fabric should be painted tight.. as if a fabric is loosely woven, paint tends to move deep through the treads before it is dry.Hence, this results in lowering down the intensity of the colors.

Tips:

Pre-washing

prewashing fabric before painting on it is to remove any sizing added during manufacture which may prevent the paint from adhering to the surface. It also gives it a chance to shrink, if it's going to. To test whether a piece of fabric really needs prewashing, drop a little bit of water on it. If it beads up on the surface, it needs washing. If it sinks in, so should paint.

Skip the Softener

You're trying to get rid of chemicals, not add new ones.

Go With the Flow

Wetting the fabric with clean water before painting it encourages colours to flow into each other, like in a watercolor. But don't add too much water, as it'll dilute the colors; the fabric should be damp, not soaking.
