Heat embossing

This was my first time heat embossing on window sheet. I need loads more practice, however, The skies the limit stamp set totally lends itself to this technique.
The plane and clouds are on the outside of the window sheet, and using the Stampamajig, I stamped happy birthday and the tail stream on the inside on the card base.
Stampin' Up! Archival ink was used as it gives such a clear, defined stamped image.
When I've had a bit more practice, I will post a tutorial.
Thanks for stopping by.
