Northants Model Makers are holding a model exhibition at Windmill Primary School in Raunds.
The event will be held on Saturday and Sunday, March 28-29. It is open from 10am to 5pm on Saturday and from 10am to 4pm on Sunday and admission is £3 for adults and £1.50 for children.
All types of models will be on show and the organisers hope to raise £2,000 for the school, some of which will pay for a theatre group to visit the school, and new photographic equipment.
The show is believed to be the biggest two-day show of its type in the area and has something for the whole family.
