Blow up 2 balloons - use a big one for the body of your spider and a small one for the head.
Spread PVA glue over each balloon and then cover them in torn pieces of newspaper. You can rest each balloon in an old bowl to make them easier to cover. Once you've added three layers of paper and glue, leave them to dry and then pop the balloon inside. take your completed head and body pieces and stick them together with tape.
Draw 8 spider legs on stiff cardboard and cut them out.
Cut out small squares from an old bin bag. Place them in rows and stick lines of tape along the top of each row to create ruffled strips. Use the strips to cover your spider's body, head and legs. once covered, stick the legs to the body.
Add patterns to your spider's legs and body by adding more ruffled strips made from coloured napkins. Use plastic bottle tops to make eyes for you spider!
Cut a hole in the back of your pinata and fill it with sweets. use some string to hang it up and then you're ready to party!
