I know you are asking about spreading and diluting but you really don't have to do that. I just finished a quilt and all I did was drizzle a thin bead on- sort of in a grid - granted I don't have any issues with holding the bottle upside down and giving it some gentle pressure. If I happened to get a glob (rare) I just used my finger. I let the glue dry and did an all over meander and the needle didn't gum up and the glue washed out. Couldn't be easier. The glue really doesn't have to cover the entire surface. Good luck with it. I hope you can find something that will work for you. To me it has become my favorite quilting shortcut.
