Everything You Need to Know About Flock: A Comprehensive Guide

What is Flock?

Flock is a unique heat transfer vinyl that gives your design an added dimension given a raised, soft, and textured suede/velvet feel that is a perfect alternative to embroidery. This makes it great for children's garments (ex. onesies) as well as adult’s (ex. team sweatshirts).

Whether you’re looking for that alternative to embroidery or going for a retro look, flock can help you achieve this. Siser StripFlock as well as Chemica UpperFlock can even be layered on top of itself! With a wide offering of colors, you’re sure to find the perfect shade to complement any design for children or adults.

In this blog, we compare the two versions of Flock (non-printable) that we offer: Siser StripFlock and Chemica UpperFlock. They are very similar, yet have some unique differences.
