i had to do a project on th endoplasmic reticulum (smoot and rough) i had to make a powerPoint presentation and a 3D model that could hang from a hook on the ceiling
i made it out of felt and qiulting pins(plus hot glue needless to say)
i made the ribosomes out of pink pony beads
(i hope i got an a+)
thanks just thought i could share!
