Families are being invited to a free Halloween mask workshop where they could win shopping vouchers.

St George’s Shopping Centre, Harrow, will hold the event tomorrow from 12pm to 4pm giving children the chance to create their own spooky character.

Once made, parents can then snap a picture and upload it to Facebook with the #STGscarySelfie to enter the scary selfie competition with a chance to win a £100 voucher to spend at a shop or restaurant.

The workshop follows the success of the centre’s recent Diwali event where hundreds of children made lanterns to celebrate the Hindu festival of lights.
