..just simple items that won't cost money??? Sorry, but i'm kind of desperate at this point, and we have no clay that i can use or anything and can someone tell me all the parts and what to make them out of- the cell wall iz going to be a shoebox if that helps!!!
You could stuff the box with tissue paper and use more paper, construction, to form the shapes you want for the rest of the organelles. Lastly, I'd just stick toothpicks in with labels made of either tape or more paper to show what everything is.
