You can make TE from NPA - same ingredients.
1part NPA + 3parts carrier = TE
A drugstore eyedropper is a good way to mix small batches. For carrier I like Everclear from the liquor store (ethanol). If that\'s hard to get in your area there\'s some ethanol/water carrier in the chemset, or you could probably get away with using vodka. Or you could mix the NPA with cologne as your carrier - small batches are recommended cause then you have your pheros committed to one cologne.
I like to spray cologne, let dry, then spray pheros on top. That way I don\'t \'seal\' the pheros in under a cologne layer - pheros are barely volatile and need all the help they can get to become airborne. I also spray in nearby but different areas sometimes. There probably no \'wrong\' way to do what you asked in 2). Experimenting/personal taste should answer that for you.
