I used an A4 sheet of 300gsm white card for the base as you need a sturdy finished box.
I used spotty card from Anna marie designs . I cut into panels to cover all the sides and back of the box. The flowers and leaves are made using punches and attached onto the box using acetate in varying heights. The birds are made using a SU punch also. I used strips of white card to form the roof of the birdhouse and used a little punched heart in the middle..Of course I used my trusty Craft-DeeBowz bow making tool to make the gorgeous double looped bow.
