Card stock in a variety of colours and with different shapped openings. Great for framing pictures,embroidery, embossing or 3-D pictures
Each set includes 5 cards, 5 envelopes and 5 cover sheets--to cover the inside of the window if you want to. This is great is you decide to use a plastic insert or if you want to decorate around the window but keep the card solid inside.
One thing I like to do with these is to get two different colors and trade the cover sheets so that I have a different color showing through the window.
