While I prefer a Slimline card to measure 3.5 x 8.5", this one is a full 4 x 8.5" to give me room to make the diamonds this size. It fits perfectly in a #10 business envelope for mailing, and this one will mail for a single stamp!
Measurements for Diamond Z-Fold Slimline Card by Karen Aicken
Card base - 8 x 8.5". With the 8" side at the top, score at 2" and 4". The 4" scoreline is the center, so fold your card in half along that scoreline. Then fold the front right flap back to the outside along the 2" scoreline.
Patterned paper - TWO 1.75 x 8.25" pieces and ONE 3.75 x 8.25" piece. I don't always use the two smaller ones, often just adding one to the front and leaving the inside one undecorated. It's entirely up to you.
Diamonds - TWO 2.75" squares and ONE 2-1/2" square
Patterned paper (BE MINDFUL OF THE PATTERNED PAPER IF IT HAS A DIRECTIONAL PATTERN) TWO 2.5" squares and ONE 2.25" square.
Signing block - 2.25" cardstock square with a 2" square of white or light cardstock of your choice.
