I can’t justify the cost of buying a giant cactus, real or artificial and I don’t have the greenest of fingers. Therefore I decided that the only way I was going to get a giant cactus was by making one. As this was a fun decor piece I decided to pimp my paper mache cacti with paper napkins. So I now have a fantastic Marimekko giant cactus and a giant pear cactus.

You will need to make a solid frame for your cactus. To do this first set your large wooden stick in plaster of paris in a bucket.
Shape the chicken wire into a cactus shape on your wooden frame.
Cover your chicken wire in stripes of masking tape, this makes it easier for the newspaper to adhere to. Cut your newspaper into strips approximately 3cm X 20cm. Paste the PVA glue onto the newspaper strips and stick to the frame until covered.
Once dry, dilute your PVA glue 2 parts glue to 1 part water. Cut your tissue paper into strips approx 3cm X 10cm. This time paint the diluted glue onto the newspaper layer and then place the tissue paper on top until completely covered. Leave to dry
For the final paper mache layer use paper napkins. Most napkins are 3 ply, separate out your napkins so you only use the top printed ply. This time don’t cut your napkins into strips but tear them so you get a feathered edge. Using the same glue mixture and method with the tissue cover your cactus in the napkins.
Finally when the napkin layer is dry cover the whole cactus with waterproof PVA to provide it with a protective finish. Water proof PVA glue is thicker than normal PVA so it's best to apply with a foam brush so as not to tear the napkins. This PVA appear white when applied but don’t worry as it dries clear.
