I made this using using Bluebell Meadow from the Tonic Double Detail Die and Stencil Sets. The bookmark can be removed from the little pocket on the front of the card.
I cut the die in white card and stencilled with gold ink then laid it over gold mirror card. I used the Tonic Square Layering Die Set to cut apertures in the brown card to create windows for the stencilled die to show through.
Using the bookmark in a book I designed the cover and many pages of!
