HTV ORDER
HTV layer order and why mirroring matters
The two mistakes that ruin a heat-transfer shirt, and how to avoid both.

Mirror before you cut, not before you press
Heat-transfer vinyl is cut face-down. If the file is not mirrored before cutting, the design transfers backwards — and there is no fixing it after the press.
Press the largest layer first
Large areas need more time and pressure. Pressing them first gives the smaller layers a stable surface instead of a stack of half-adhered vinyl.
Watch the temperature per colour
Different vinyl brands and finishes have different press settings. A layer pressed at the wrong temperature either lifts or scorches, and both are visible.
