I have 3 tables in my room. Each table can seat 8. I am not sure how to have the supplies. Part of me is thinking that with one container in the middle everyone can't reach it. BUT, if I do two containers of supplies it will take up lots of room on the tables. I need the container(s) to hold pencils and crayons for sure. I could store scissors and glue elsewhere and pull those out when needed or have those on the table all the time like the pencils and crayons. If you do communal supplies what sort of container do you use??? Thanks!
