Hi Stephen

      I have my displayed two ways. First I use glass aquariums in which I
built different levels with boxes, etc., cover in cloth the covers of the
tanks help keep a lot of dust out. Also the aquariums are very easy to cover
with a cloth to keep the sun off if need be. Other wise put in a conner out
of the sun.
     The second way I am still working on I just got a large glass store
cabinet fore glass shelves and one wood. Basically the same idea I am useing
a sheet to cover it to block the sunlight. To hold the shells in place I use
a doll house wax called Mini-Hold that will not damage the shells, I have
used it for years and it comes right off. You can get it at any doll houses
store. Labels I just make out of cut index cards and hold them in place the
same way.
     Hope this gives you some ideas.
