This is how to make it:
First put the flap of one of your envelopes inside the other one and then glue them together as shown on the photos.
Before covering the inside flaps with paper in a similar way, I ran them through a Texture Fade embossing folder to add texture. I then stamped some images from the Insects and Butterflies 1 set and the Birds of a Feather set in Archival Ink Jet Black, fussy cut them, coloured with water colour pencils and then after the papers were stuck to the envelopes, used them to embellish my project. I'll let the photos tell the story of how ☺...
Perfect Pearls Heirloom Gold added some sparkle still and I rubbed some gilding paste over the raised ambossed bits.
I then made a die cut tag to fit inside one of the pockets and inked and stamped it in the same way using the Birds of a Feather set. Again I coloured the images with water colour pencils and added shadows around the images to add depth.
Caterpillar Words in Jet Black Archival again and finished it all of with some roses and a piece of String to tie it shut.
