I use my teacher id card, every year I make id cards for the kids also so they get the student discounts as well, the art store dick blicks gives a good student one and that is great for color pencils and good paper.
On the card --
We have our school name in italcs bold
with city and state next to that smaller font
the school year ie 2003-2004 our family crest (that is the shield logo)
a shoulders on up head shot pic of the person sized down on the home puter down and glued into lower corner gently
that persons name in a dif font
all in a traditional size id card printed out on the home computer
I get the 3-M things that plasic coat/laminate and seal them up for a couple bucks at the drugstore and that is our id for the year, that is all the id I have ever shown at any of the places mentioned above and I was given a discount no ? asked. also used at the movies and on the bus/metro, also presented at the library, used these in at least 15 states of the US while traveling, even at the national parks camping. Joanns you can do online and it is much easier plaus you get more coupons that way.
