How can I purchase these digital files?

These are brilliant. So simple, yet incredibly clever. Seeing your "House Corleone" one made me think though... "House Soprano" "Family, Therapy, Cash"

Do you have a free template to use?

Ideas:
House Stirling (sigil - a brown violin on silver with white flowers) "Freedom and Joy" (Real Life)
House Grey (sigil - an argent griffin segreant on azure) "In War, Victory. In Peace, Vigilance. In Death, Sacrifice" (Dragon Age)
House Mac Tir (sigil - a yellow wyvern on black) "Son of the Land" (Dragon Age)
House Stormcloak (sigil - a wolf head of gold on azure) "Be True With Your Blood" (TES V Skyrim)

These are great, nice work! fan on most places so double thumbs up!

These are amazing!
