a paper lantern (mine is an 18" "regolit" shade and "hemma" cord set from ikea)
a whole lot of coffee filters (mine ended up needing around 700)
1. inflate paper lantern
2. separate coffee filters individually
3. smush coffee filters
4. glue them one by one onto the lantern in rows.
progress photos (left is the first row and right is after 400 filters)
and up in my living room.
the best part of this is that i was working on it over break and kept having to come up with a name for it. my niece first asked what it was, the room went quiet, and then i said it was a lampshade. she accepted this and started petting it. (it has since been called "the poof" and "an art object" as well.)
