I used the calendar stamp, one of the fabric ATCs and some of the cardstock border stickers, and here's how I did it:
First I took the ATC and inked it with Antique Linen Distress Ink to give it an aged look.
Next I peeled the backing from the ATC and stuck it to some brown cardstock which I trimmed down. I then inked the calendar stamp using dark brown ink, being careful to only ink the areas that I wanted to stamp (I had a babywipe to hand though, just in case!), and stamped the image to the top of the ATC.
Then I cut some sections from the border strips and layered them up along the bottom of the ATC. And there you have it, your very own calendar embellishment!
