Create nine different types of A1 sized cards that all fit perfectly inside the included A1 envelope. You get everything pictured, including seven styles of flat cards - heart, oval, scalloped oval, rectangular zigzag, rounded rectangle, rectangle and scalloped rectangle. You also get two styles of folding rectangular cards. "4 Bar" (also known as "A1") is a specific size of card and envelope. The cards measure 3.5" by 4.875" and the envelope measures 3.625" by 5.125". You can of course cut each element at whatever dimensions you desire, but they're already sized at A1 and a helpful instructional PDF document is included.
