Turn any fabric into a writable surface with Siser Blackboard! This new heat transfer vinyl transforms ordinary T-shirts, garments and other heat sensitive materials into walking chalkboards that can be used over and over. It’s lightweight, soft and only needs 275°F of heat with medium pressure for just 15 seconds to create a machine washable chalkboard!

Siser Blackboard is compatible with standard chalk, and it’s just as easy to re-use as it is to apply. Simply wipe clean with a damp cloth to start over!
