Hello,
A couple of days ago, I made a card with Spellbinders Susan Tierney-Cockburn's Cymbidium Orchid And Ladybugs Etched die. The dimensions of the orchid is incredible!! But it will require special packaging to send thru the snail mail system.
Today I made a version that's snail mail friendly. I minimize the shaping of the flowers, and I place the arrangement inside a raised rectangle frame (attached to card base with 1/8 inch thick foam adhesive). So, even when the card is pressed down, it has at least 1/8 inch of buffer.
Here's the card before I put the card inside the envelope.
