Baubles made from Concertina Paper
Each bauble is made from two half circles cut from concertina paper. Each half circle is then spread out into a half bauble. These are then glued together to make a complete bauble.
1
Cut two half circles from the concertina paper to make one bauble. NB: the paper direction should be horizontal because of the lines in the concertina paper's layers.
2
Spread out one half circle to form a half bauble and attach double-sided adhesive tape. Now spread out the other half circle. Attach this to the other half circle to form a complete bauble.
