Mrs Parrington said it was easy enough making the pillowcase dresses last year so decided to use the same concept for the pyjama pants.
"To be honest the dresses were probably easier to make," she laughed. "I used a normal pyjama pattern but it was a bit more fiddly and sometimes hard to get the right length for the bigger children."
Along with a team, Mrs Parrington will travel to Pattaya on Tuesday to personally deliver the clothes.
"It feels good to use the little gift I have to make a difference in people's lives around the world.
"I love children and I love making something out of nothing so these projects are the perfect combination."
Mrs Parrington has plans to make reversible skirts to send to Vanuatu later this year. To donate unwanted pillowcases, contact the Living Well church (07) 348 7932.
