Sometimes you find that perfect project and the supplies are nowhere to be found. There are some great online sources.
http://www.createforless.com/ has some great things (you have to search a bit). Check out their great selection of pipe cleaners!
http://www.happytape.com/ for Japanese masking tape. I haven't jumped on the bandwagon of this fad, but they really are lovely.
http://www.save-on-crafts.com/ Twine, millinery, scrabble tiles (much cheaper than buying the game for them, trust me!), seriously tons of stuff! You have to search around quite a bit, but it's hiding in there!
Tiny masking tape at http://www.ssww.com/!
http://www.ornamentea.com/ has these gorgeous felt balls and lots of little bottles and very cool items!
Of course, ordering online means that you've planned ahead. Not usually the case for me! My favorite local sources are: Paper Source (in Bellevue), Paper Zone (sodo), Impress (U Village, Bellevue Square, near Southcenter) and Michaels and Joanns are always the old standbys.
