In a bid to build understanding about the condition, schools have signed up to Epilepsy Tasmania's Purple Finger Knitters' School Challenge.

The organisation's chief executive officer Wendy Groot said students were planning to decorate buildings or pieces of play equipment with their finger knitted creations during the month of March.

"Finger knitting is quite the thing at the moment so we thought we'd encourage children and schools to do something creative," she said.

Throughout March organisations will also sell merchandise to raise funds for Epilepsy Tasmania.

"There's lots of schools, organisations, workplaces that want to be part of it so they get the merchandise and they sell it on for us," Ms Grott said.

Trevallyn Primary School is among the schools going purple and Principal Annette Hollingsworth is already thinking about how to showcase students knitting efforts.

"We've got some lovely tree trunks, the environment's very important so trees are jumping out as a natural prop for me at the moment," Mrs Hollingsworth said.

Last year, Trevallyn Primary became the first epilepsy smart school in Tasmania after staff successfully completed a unique training program in response to student need.

"There's something so special about a whole school knowing how to respond to a disability, it's just another feather in our cap, it's another part of learning," Mrs Hollingsworth said.

According to Epilepsy Tasmania, one in 200 school students and a total of 20,000 Tasmanians live with epilepsy.

"Epilepsy first aid is really, really important because there's more than 40 different sorts of seizures," Ms Grott advised.

"It's really important to know what to do to help somebody if they have a seizure."

In addition to the knitting challenge, Epilepsy Tasmania has planned a photographic exhibition to raise further awareness.

Podcasts which highlight stories of people who have epilepsy will also soon be made available.
