Here's my go:
I didn't really know where to go with this one so I started by digging out some postage bits and pieces from my stash. I found a bunch of postage stamps that were leftover from the September Quirky Kits, a shipping tag, a postmark clear stamp and I had a postage stamp die, (it's the Cuttlebug one that came free with the machine when I got mine a few years ago). I picked out a yellow patterned paper, (October Afternoon) to go with the tag and added it to the card blank front. I then had a play around picking out stamps and there wasn't one that I didn't like so I ended up sprinkling them all over the background. I used the die to cut a window out of the tag and put a little bit of paper behind it, (chevron is a yellow paper bag). The tag is fixed to the card with foam pads then I just added the extra stamp with the postmark stamp in the corner in a soft iridescent ink and finished it off with the message printed onto white card and cut out.
