i enter quilts in the fair every year- it is great fun! and i have quite a fun collection of ribbons!
pick up a (fair book) it will tell you the requirments, the drop off pick up times...and what if anything you might win--(i've been lucky enough to win the Viewers Choice award 2 years in a row---the (prize) was a gift donation in my name to the area food bank (manna)- a nice certificate and the ribbons...
go for it-it is a good experience.
