I think the library should make a makerspace in the new room. This is my choice because it is something new and useful for the community.
Nowadays many people want to learn how to make things by themselves. But 3D printers and sewing machines are very expensive, normal families can not buy them. If the library have these machines, everyone can come and try them for free. For example, my daughter is twelve years and she is very interesting in 3D printing, but in our school there is no printer. She can learn a lot in the free workshops.
Also, the makerspace is for all ages. Old people can teach sewing to young people, and young people can help old people with technology. I think this will make the library more lively and bring more visitors.
The quiet study room is also good, but in the library we already have many tables for reading. Students can study there or in home. A makerspace is more special.
So please choose the makerspace.
