The quilt store I was at last year had small empty bottles with a tiny metal tip. Also, in the section of hobby lobby where they have the model cars, there were some small plastic tips you could put on a bottle but I'm not sure what kind of bottle they fit on. I bought the tips but am not sure what bottle I was planning to use them on. I also bought one of the empty bottles at the quilt shop but as of this moment, I have no clue where it is. I saw it recently but then put it somewhere (probably somewhere safe where it wouldn't get lost) and now I can't find it.
