Commonly asked questions.

Which iron do I use for heat-sealing? 

We have used both the Jamara Pro Star iron and the Prolux Digital Iron. We’ve had far more consistent results heat sealing with both of them, although it should be mentioned they are far larger and slightly inconvenient to work on the smaller seams and tight areas. This is where this Smaller Electric Iron comes in, it maintains its temperature well, making it a brilliant iron for tight areas.

What is heat-sealing?

All our fabrics have a technical coating called thermoplastic polyurethane (TPU). This coating makes it possible to essentially stick the fabric together without having to mess around with glue! The TPU coating can be activated when heated with hot air or an iron. If you hadn’t guessed already from our name- we use an iron. Take a look here for more information on ‘what heat-sealing is’.
