Our 100% Polyester and 65% Polyester 35% Cotton Polycotton Blend materials are base fabrics for our sublimation baby blanks. The interlock knit is more stable, durable, and has a "cotton feel". With crafters in mind, our infant sublimation blanks are also an ideal canvas for a big variety of decorating methods like embroidery, screen printing, applique, HTV (heat transfer vinyl), and more.
