First I'd like to thank Kerry's Paper Crafting Blog for this great idea!
The container I used is a blueberry container, so it's a little thiner than others. But it's still perfect enough to fit some wonderful little suprises inside. I put a gift card next to it so you can see the size. I think it would be a perfect fit for a gift card and some chocolates.
The larger/deeper ones are great to put some votive candles in. Great for Christams, Birthdays, Teachers Gifts...Just use your imagination!
