It's the biggest fundraiser of the year for Big Brothers Big Sisters Sarnia-Lambton.
Over 100 vendors will line the halls at Alexander Mackenzie Secondary School for the 47th annual Show and Sale Saturday and Sunday.
Spokesperson Kaylen Burgess said there are 20 new vendors this year selling everything from jewellery, pottery and Christmas decorations to baked goods.
She said all proceeds will support Youth Mentoring Programs.
"Last year we served just under 600 youth in Sarnia-Lambton and all that money goes right back into and stays in the community," said Burgess.
The Show and Sale runs from 9 a.m. until 5 p.m. Saturday and from 11 a.m. until 4 p.m. Sunday. Admission is $5.
