I have put a vellum envelope inside so that some money can be added. The tag is there so that the envelope will still have something in it once the money's been spent.
I used Stazon to stamp the image onto the vellum and back of the tag.
These are great to work with. Little Birdie is printed on photo paper and 3D'd onto brown paper. The card is covered with PP from Poundland.
Thanks for looking.
