• Tension. Set. Repeat.: A gold skull, a couple of lightning bolts, and the three words that sum up a night at the picking bench. The gold really pops against the black.
• Thou Shall Not Contain Me: This hooded skull looks like it has a personal grudge against locked doors. White on black, with a little delta on its forehead and a whole lot of attitude.
• The Carpet Demands a Sacrifice: A grim reaper, extra skulls, and a tribute to every tiny spring the carpet has claimed. Black on gray—for anyone who’s spent more time searching the floor than reassembling the lock.

Iron-On Application

1. Check that your fabric can tolerate heat. Position the patch adhesive-side down on clean, dry fabric supported by a firm, heat-resistant surface. There is no clear protective film to peel off.
2. Cover the patch with baking parchment paper (not wax paper), a clean, dry, thin cotton cloth such as a plain cotton handkerchief or a single layer of a cotton pillowcase, or a Teflon pressing sheet. Keep the patch fully covered; avoid thick towels or synthetic cloth. The blank supplier recommends a heat-press starting setting of 280°F (about 138°C) for approximately 16 seconds. Test first and adjust for your fabric and equipment.
3. If using a household iron, use dry heat with steam off and steady pressure through your chosen protective paper, cloth, or pressing sheet. Iron settings vary; the supplier's heat-press timing is a starting point, not a guaranteed household-iron setting.
4. Let the patch and fabric cool before checking the edges. If needed, repeat a short protected press. Avoid direct contact between the hot iron or press and the artwork.
