Branches on the edge of cards are using a Clarity stamp stencil, and the tree trunks in the background of another are also from a Clarity stencil.
The woodgrain effect was done using a Sizzix embossing folder, inking it up with brown ink and then pressing a sheet of paper over the top - I repeated this 3 times to cover an A4 sheet of card, so that I could cut out two 6"sq pieces. Distress inks in brown and green were randomly sponged on the card to create a weathered effect, then i used a small circle die to cut the nest hole out.
The cut out bit was sponged with darker inks, then glued in place on the base card - place the main piece of card on the base first, then glue the cutout into the hole to make sure it all fits properly. The big owl was glued onto the 'hole' piece, the the main piece of card glued down and the baby owls perched on the rim of the hole. Remaining big owl sits on a diecut branch from the Stampin Up bird punch.
