This was one of my projects last month - I just didn't have time to post it 'til now. But it is usable for any time- just change the color and sentiment.
Take a cardstock 8 1/2 inches x 3 inches and score from the top 2 3/4" and punch the large oval as shown- here I used wild wasabi cardstock and stamped the sentiment in expresso. I added the piercing to add some interest. I embossed the bottom 1/3 again to add some interest and then layered some coordinating paper. Stamp the drink of your choice and decorate it however you want. Punched it out using a circle punch but you could use any shape that fits your event, layer it if you want too.
