Siser EASY WEED Vinyl Heat Transfer material is a thermoweldable PVC-free material for CAD application onto non-siliconized textiles. Much thinner than standard materials. EW offers excellent wash ability as well as durability, and is extremely easy to cut, weed and apply. Because of the thinness, excellent performance can be achieved with single or multi-layered applications. EW is a unique pressure sensitive carrier. This feature allows you to apply small letters and fine designs easily.
