Is it necessary to heat set my block printed project when using Fabric Creations™ Soft Fabric Ink?

Heat setting is recommended for best durability.

Heat set the painted surface using a dry, hot iron and a pressing cloth. Lay pressing cloth over the stamped fabric and iron the stamped design for 30 seconds, lift the iron and move it to another section of the stamped design. Your iron should be set at the highest setting allowed for the decorated fabric, no steam.
