I presume you mean to create a "virtual craft room" for poser, if not the rest of this reply is useless lol

i dont think it will be too hard to assemble dani, there are any number of legit free 3d tables, chairs models, some may be  in import formats like 3ds or obj files, but i would imagine a search on sharecg would fill your room pretty quickly. Any standard wall and floor will work, for ease I would just apply an image to the wall material to represent the notice boards full of clippings, simple square primitive props from the poser folder can be used for the paper on the desks. there are some craft scissors on sharecg also, just click on poser and enter scissors in the search window.

Sellotape or rolls of tape could be replicated using basic cylinder props depending on how close up you want to view them.  the primitives folder is great really, you can do loads of fun stuff with them with a bit of tweaking :)
