I've used a Gruffies stamp to create a beach scene, and added a sentiment I generated on the computer.
I added photo corners to the image to make it look like a holiday snap, but then wondered what to use for a background. I really wanted it to look like real sand. Paper..... sand...... SANDPAPER! Yep, I raided the tool box and found a sheet of unused medium grade sandpaper. It was even worse than glitter card to stick the pieces down on though, I ended up using industrial quantities of Pinflair glue after experimenting with every other adhesive in my (extensive) repertoire. So I don't think sandpaper is going to become a regular feature on my cards, I can't afford that much glue.
Now let's see your beach themed makes, the snarkier the better, and pop over to the Sisterhood to share your makes and give the sistahs some crafty love.
