Hello! The idea has been settled for souveniers, we're going with the candle carving one :)
So we'll be carving invest theme, guest school name, 310309, thank you, CGSSC on the candle, like top bottom one side other side. Because customising it plus it's hand- carved shows our sincerity hehe, and also other ideas like no.2 has been used by other schools from previous years. Yup it's the cheapest, and its not that hard to carve either.
We tried it already, and it looks okay
In total it costs $26.10, so we have alot from our budget left. We'll continue with everything after sec 3's common tests. Good luck everybody :)
