The definition of a one layer card is a single piece of card stock with no added layers. These cards are completely flat and perfect for mailing. Adding a die cut or two and embellishments to your one layer card is completely acceptable in my opinion and still "counts" as one layer card.
Many stampers struggle with one layer cards, so I thought I'd share a few things that I keep in mind when creating one layer cards.
First and foremost, you need to have flow. Flow helps your eye move around the design. I created flow on this card by stamping from the bottom left to the upper right of the card. You also want to make sure you have grounded your images, otherwise they will look like they are floating in outer space. You can do this by stamping a border, adding a stripe of card stock or patterned paper or adding score lines.
Lastly, add a special touch. This will vary from card to card. To give my card a finished look I rounded the corners. It's just a little something, but it definitely makes a difference.
This card came together so quickly and easily that I was able to flip the design and make another card in about five minutes!
I hope you'll give the one layer card a try!
