This card features the Clearly Thanks Printed Window Sheets (item #115122). You get two 8.5x11 sheets of acetate printed with four patterns. Each pattern is 4.25"x5.5", sized to fit on a standard card front.
This card is super simple... I layered the window sheet portion onto a Kraft card base, then punched flowers from coloured cardstock (Rose Red, Tempting Turquoise, Summer Sun and Certainly Celery) with the Trio Flower Punch. I used the brads through the flowers to attach the Window Sheet to the card base.
