CORNER FOLD CARD 

DIAGRAM OF

THE FOLDS

AFTER YOU SCORE YOUR 2 3/4 INCH LINES ACROSS AND DOWN. MEASURE FROM THE TOP CORNER 5 3/8 INCHES ACROSS AND PLACE A TIC MARK. DO THE SAME ON THE 8 INCH SIDE DOWN TO 5 3/8 AND PLACE A TIC MARK. NOW FOLD IT BACK LINING UP WITH THE 2 3/4 CENTER

Here I used a card that has a solid background on the inside. Where the triangles are I used a pale blue card stock on the diagonals and 4 1/4 x 5 1/2 section then added my sentiment.
