Students set out sustainability stall.
IT students from Stockton Riverside College took part an event to promote social enterprise.
The classmates were tasked with coming up with a sustainable product to sell, with one team designing their own reusable bags and the other making handcrafted gifts using natural and recycled materials.
The students then tried to sell their wares to the public when they took over two stalls at Stockton Market.
Patrick Duffy, 17, of Sedgefield, said: "We put our heads together and came up with the idea of making reusable bags."
He said they proved popular on the day - with just a handful left at the end of trading.
Jamie Henderson, 18, of Thornaby, who was on the team selling gifts said: "It's been interesting and very different to what we would usually be doing in class."
Team mate Sunnah Mahfooz, 17, of Stockton, added: "I have enjoyed it."
Tutor Julie Wilson said: "This has been a great opportunity for the groups to work as a team."
She added: "They have had to learn about sustainability and also handling money."
The cash raised will go towards a day out for the students.
