Would Nike be able to sue me if I created a sweatshirt with their logo and, instead of selling it, gave it away as a prize for a raffle?

The question

I'm a student with no affiliation to nike and want to come up with a way to monetise some of the clothes I create. I sometimes use an existing brand's logo as a base then add my own art to it. I know I can't sell these, but would i get away with offering them as a raffle prize. I am in the UK. Thanks for your help!
