I embossed pretty flower stamps from Paper Source that resembled the peonies on our invitations onto plain white envelopes. These envelopes will be used to hold our STD cards and the RSVP cards we want our guests to send back.
The flowers on the right in the picture have the powder on the ink and is a lighter color. The flowers on the left have been set with the heat gun and are nicely raised and defined.
Sorry for the low quality photos, but you can see it better in person when they arrive in your mailbox.
My next project will be the actual STD. I have lots of plans running through my mind and I'm excited to see the end results.
