Which iron to use
Stamping cube packs
Cube packs are short and square, so they stamp best on a short bar. The 4-inch cube bar iron is built for cube packs, single stamps, and two-stamp work. The Deluxe mini and Deluxe Plus mini also stamp cube packs, along with 6.4s and any sliding-transfer work. All three are thermostatically controlled and preset for stamp transfer.
