Confession-- a lot of my cards are made for my grandchildren -- who can't read. I use my stamps so that it is easy for them to identify a card for them in all the mail that comes to their house. The following is a long list (in order of use) - but it took me less than 10 minutes to stamp all these!
Small Cat Silhouette
Heart, Moon & Stars
Rectangle Marquee Frame
First I'll start with the fancy one - I used the Daffodils stamp and embossed it in gold. First one plain, second colored with copics. If you decide to use copics - be sure to insert a scratch piece of paper while coloring - copics will go thru the envelope.
Be sure to check out all the Banners - there are a good many scattered throughout the Repeat Impressions on line catalogue.
Here is a third group - some of these are copic colored.
Two last ones - one a banner the other a marquee.
Hope you start using your stamps on your envelopes and having as much fun with your stamps as I did. Thanks for looking at my project.
