Kalsien....I does sound like alot of fun! I may not be the besst person to advise you in the area, but here goes....

When I think of items at a fair I think of things that aren't too expensive that almost everyone can afford to buy...things like potholders, placemats, table runners, coasters, mug rugs, tote bags, bookmarks, small purses for little girls, quick baby quilts, tummy time mats, tissue covers for the purse, covers for electronic gadgets (Kindle. etc). A lot of these items can be made from scraps or small amounts of fabric. There are some great tutorials on how to make fabric flowers...make some and put pins on the back so they can be used on purses and jackets. I'm sure you will get many more ideas here.....Good Luck!
