We used these great cut out shapes I found at Dollarama. They had flowers, dinosaurs and butterflies. I picked up the flowers and dinosaurs. We tried this with both. The dinosaur didn't look very good so I'm posting the flower. Of course you could cut out our own shape to glue the tissue on.
A cut out shape to glue the tissue on
Tissue paper cut into small squares (or like me you can cut up streamers)
Paintbrush (for spreading the glue)
Adhesive magnets (optional)
Put glue on shape and spread with a paintbrush (we did one section at a time so the glue wouldn't dry out).
Scrunch up a square of tissue paper into a tiny ball and put on the shape.
Once dry, stick the magnets on the back and display on your fridge!
