You should have these three things upon returning home:
Open up one of the cardboard sleeves and lay it out. It's a pattern! Think to yourself: couldn't I have just swiped one of the sleeves and saved 4 dollars? But then how would you see your finished product on a real cup?! If you feel warm and caffeinated, move on to step 2, if not, please repeat step 1. =)
Step 2: Find two pieces of fabric to make your cozy with. Lay them on top of each other, and using your cardboard sleeve, cut around them. Leave about an half-inch or more for seams.
Step 3: This cozy is reversible. Embellish one, or both sides. Remember to stay away from the edges because we will be sewing these soon and they will disappear. I spelled out "hot" on mine =)
Step 4: After you are done embellishing, place your two pieces, right sides together in a sort of sandwich.
Step 7: Fold down remaining edge and pin.
Step 8: Sew all the way around the top of your cozy, on the front. =)
Step 9: Wrap your cozy around the cup (see I told you you'd need it!) and pin one edge over the other. Sew down on top of the stitches from step 8, making a circle.
Step 10: Admire your cozy! Place in purse and use next time you are out! =)
