£2 will be given to the children's charity for every Rachel Ellen Designs T-Shirt bought through fundraising app.
Rachel Ellen Designs has partnered with the T-Shirt Booth app to help raise money for the children's charity, Rays of Sunshine.
The new app created by Digital Giving is designed to help raise money for various charities by enabling consumers to create personalised t-shirt featuring their favourite brands, along with the logo of its affiliated charity.
At lest £2 from the sale of each t-shirt will be donated to the affiliated charities.
Rachel Church, director at Rachel Ellen, said: "We are delighted to be involved in this project. T-Shirt Booth have come up with an easy to use app which gives the end user a totally bespoke, quality product.
"Not only that, the chosen charity receives a donation and we are so pleased to be paired with Rays of Sunshine which is such a worthy cause."
CEO of Rays of Sunshine, Jane Sharpe, added: "T-Shirt Booth is a fun and simple idea and Rays of Sunshine is delighted to be involved.
"What better gift could there be than one which will not only delight a child but also help make a wish come true for a seriously ill child in the UK."
