The front of the "envelope" shows some fire crackers from the Sue Hillis It's Summer chart. The alphabet is from a freebie by Victoria Sampler. The address is her business address, so don't worry that I didn't block it out.
The inside was lined with fabric that had firecrackers on it, and I enclosed a postcard of Chicago.
To say the Sue loved it is an understatement! And she reported that it arrived in perfect condition.
