I have a little trouble squeezing the bottle for the length of time it takes to do the job, so I experimented and diluted the glue until it would spray a fine spray out of a spray bottle. I used warm water...not sure if that made any difference but I think it 'softened' the glue a bit. I just sprayed, then rubbed my hand over the batting and joined the two layers together. I have done all of my last quilts this way and it is wonderful. I lay them on the bed and can get them REALLY smooth AND don't have to worry about overspray. When I'm done I take the sprayer part off the bottle and run some warm water into the sink and dipping the end into the warm water I spray several times to clean out the sprayer. Put it back on the bottle and you are ready for the next time.
