Bag4Sport turns textiles collected by participating groups into cash to pay for coaching and equipment.
Anyone aged 16 or under who belongs to a sports club, school or other youth organisation can enter the competition and be in the running to win £500.
The charity was launched two weeks ago by Olympic gold medallist Tessa Sanderson and aims to raise £100,000 over the next year to help grass root sport and budding stars of the future.
Joint founder Andy Trusler said: “The winning T-shirt design will play a big part in our promotional work. We are looking for something creative that catches the sporting theme.

“It can be abstract or symbolic like some of the artwork for the 2012 Olympics or it can be a more real life representation of sport. Everyone will have a different idea and we will be looking for the most creative that captures the work of the charity.”
Bag4Sport was started by Mr Trusler and Jide Ihenacho as a way groups could raise money for equipment by collecting unwanted clothes. The bags of textiles are collected and weighed and then recycled for cash by the not-for-profit organisation.
Now the charity arm of the organisation is taking fundraising to a new level. Mr Trusler said: “Some of the entrants may want to include the recycling element in their design as this is still very much part of our work.”
