I use the following visual aids or "props" when I give presentations on Y'shua in the Feasts of Israel.  It helps people to remember better  if they have some visual reminder of what is associated with each Feast.  If you are giving your own presentation, you can be creative here, and use whatever you have handy.

seder plate, shank bone, roasted egg, parsley, charoseth, stuffed toy lamb, matzah tash, wine cup, horseradish root, matzah, Elijah's cup

I used an avocado, but any early harvest fruit could be used -- rhubarb, artichoke, etc.

two challah rolls or loaves, small Torah scroll

  shofar

DAYS OF AWE

three books, a small white one for the godly, 
a small black one for the wicked, 
and a very large red one for the sort of good/sort of bad

tallis, small rock, shofar

small model of a sukkah, basin and pitcher, lampstands.
