I just bought a small vacuum cleaner from nancy's notions for this but the attachments on it aren't very small either. I'm disappointed because that's obviously what they sell it for, but they won't even fit down into my bobbin area enough to suck anything out. I haven't decided yet if I want to return it (will cost me $$ because I'd have to pay to ship it back I'm sure plus not get shipping I already paid back) or try to tape something on it that will take smaller attachments. The way it is now, the hose end is not even round (it's a moon shape) so I can't use my existing tiny attachments on it. My attachments won't fit on my regular vacuum cleaner either.
I thought that you shouldn't blow air into it or you risk forcing the dust in even deeper. I know I read that somewhere...
