Flannel

Flannel starts as an ordinary plain- or twill-weave cotton fabric, then goes through a brushing process where fine wire brushes lift and break thousands of tiny fibers on the surface, raising a soft fuzzy layer that traps air for warmth. Typical apparel flannel runs 4 to 6 oz for shirting weight, woven in the classic plaid patterns from yarn-dyed threads so the color pattern is baked into the fabric rather than printed on.

It's the fabric behind flannel shirts and the softer, brushed-back linings some brands use on cold-weather pieces — customers reach for it specifically for that lived-in, soft-hand feel that a smooth broadcloth or twill doesn't have.

That raised nap is exactly why screen printing on flannel is a compromise — ink has to bridge over fuzzy, uneven fibers, softening fine lines and small type, and it often needs an extra flash cure to seat properly. Embroidery doesn't have that problem; stitches sit on top of the nap rather than needing to penetrate a flat surface, so a logo or monogram on a flannel shirt reads clean.

Shops sometimes screen print a detailed logo on flannel expecting tee-shirt sharpness and get soft, feathered edges back. If the design has fine text or thin outlines, we'll steer that job to embroidery every time — the nap just won't hold a crisp printed edge.
