Ah you have a letters project that you want, yes? Preferably using those lovely black and white stills, of everyday objects shaped like letters but you don't want to go out and buy them? Well if you follow this link, it'll take you to a Flickr site in which friends--you can download and print (for non-commercial purposes) any and as many photo letters as you please.
Free letter templates to print from your printer. These will be great to use on a bulletin board, lots of letter choices.
