that you for posting this, it helped me greatly. where do you pick up those cleaning pads? i'm just working on using blending stumps with my work now, i used to use tissue with the ends twisted up (i still find myself using them from time to time)
Uh, any art store which caters to professionals and art students should have them. My local ones are Blick (which also has great online selection), Utrecht, and (formerly, it close a month ago) Pearl.
