At Christmas time?
BUT..... the challenge did say you could use the color, and this color definitely looks like sand to me.
Here is the challenge at less is more. "You may decide to use the colour, the texture, scenes of sandy places, sandpaper, actual sand... or wherever your imagination takes you."
I guess my imagination took me to Christmas! I have been making a few Christmas cards each week to send to Operation Write Home. This is one of them.
I used the stamp set Shadow Tree from MB and embossed in white, then tied some bakers twine on. The paper is SU white and kraft.
Hope this fits the challenge!
