Speedball Fabric Block Printing Extender Base 2.5oz

Speedball Fabric Block Printing Ink Transparent Extender Base is a non-toxic, oil-based additive designed to increase the transparency of Speedball Fabric Block Printing Inks without thinning their consistency or tack. Ideal for creating sheer color washes, subtle glazes, and smooth layered gradients on cotton, linen, polyester blends, and rayon, it dries to the touch overnight and cures permanently within seven days with no heat-setting required, while still cleaning up easily with warm water and soap.
