Sarah Callaway, and Mike Pitman, came up with the idea for House of Callaway, which sells several different types of menstrual cloths while at university.

Used externally, reusable menstrual pads are generally made of cloth and are available in a variety of shapes, sizes and designs. Once used, they can simply be rinsed and thrown in the wash before being used again and again.

Mike said: “We set up the business while balancing our university studies, and as it was our first shot at setting up an enterprise on our own, we were in need of practical help and advice.

"Big Ideas Wales put us on a one-to-one course with an advisor, who talked us through all aspects of creating a successful start-up. We went through everything from small things like formulating an ‘elevator pitch’, to big tasks such as our long-term marketing plan.”
