DIY set of hedgehogs. Make them with this set of pipe cleaners. In the bag is a QR code that links to a tutorial video.  
You will need to have a glue gun (a glue stick is included in the kit) or strong material glue. 
Scissors to cut the pipe cleaners 
A sharp crafting knife to cut the polystyrene. 
(The video shows using a sharp blade, I ABSOLUTELY DO NOT recommend this) 
(Double sided sticky tape is also suggested as an alternative to glue)
Please be aware the pipe cleaners (chenille stems) can have sharp ends. 
This is not a toy
Not suitable for small children
