So here is what I recommend: 1. Use the Internet. Google/search for fairs in your state using key words like "Connecticut" and "fair." Then see what is close to you. Of those that may be, add to the search "sheep." Usually if animals are part of the fair, this is a good sign that fiber arts will be too. Next, add "crochet" to see what hits you get. You may get none. If that's the case use "knit." If you get "knit," visit that webpage and send an email to the "CONTACT US" folks. Ask for someone to contact you about entering into their needlecraft competition.
2. Check with your local yarn shops. Some sponsor prizes for the fair(s), so they'll usually know.
3. Check with your local crochet and knit groups both locally and online.
Once armed with all the information, if you're not ready to enter this year, still go and check out what is being submitted. This will give you an idea of what type of entries they're looking for, the space they have available for displaying various works, how it is protected from the public, and it gives you an opportunity to ask questions in person.
Next, Karen inquired about the mannequins that my work was on. Is it necessary for me to provide them? The answer is NO. I have been entering the Bridgewater Fair since 2001, and it wasn't until last year that I inquired with the coordinator if she'd like for me to use them. She was thrilled as she said, "it adds more dimension and interest to the display." I strongly recommend you inquire and get the OK first before submitting items displayed on your own mannequins.
As to where I got my mannequins -- that I have Mr. Dee to thank. He found a store remodeling and asked what they were going to do with the old store displays. They opted to give him the mannequins rather than toss them into the garbage bin, costing him nothing to obtain them. Most stores remodel every 10 years or so (it's written in most rental agreements that the store stay "fresh" with the times), so ask! The very worst you'll hear is "No," the very best is "Yes." If you can't wait, then check out sites like ebay.
No matter what you opt to enter, do ensure all your ends are properly woven in, that your work is clean and blocked. Your work is being judged so you'll want it to look it's very best! If you win a ribbon, that's great! If it doesn't, that's OK too -- someone may have been inspired to try crochet when they looked at your entry and that alone is priceless!!! :)
Bridgewater Fair. The weather was beautiful as we checked out the animals, did some shopping, ate, enjoyed some of the rides, and (for me) was inspired while checking out all the needlecrafts entered into this year's competition.
Yes, all of my entries earned Blue Ribbons -- setting a new record for mother & daughter (seven Blue Ribbons total), but best of all, as it was reported to me by the coordinator, people were talking about my entries, especially my vest, crocheted to look like knit, which caused a bit of controversy! 
Mom said I should tell you all about the project I submitted to the fair this year. I crocheted a jumper for a doll my Grammie gave to me. (She wrote about her love for me all over the doll's back and tummy!)
Getting back to this vest, it is true. It was inspired by points being taken off of a crocheted garment I submitted to a fair for not having the ribbing knitted. I will admit that seeing those remarks on the feedback sheet from the judge was very upsetting at first. Why should something entered into a crochet competition be fined for not having parts of it knitted? Long story short, and a year later, the answer was revealed: the judge admitted to being biased towards knit and thought knitted ribbing would have made the garment look better. Ahhhh Ha! 
Bottom ribbing was done first, with Tks built up from there. The back piece was finished first. When the front piece was ready to be finished off, I kept the stitches "live" by going into each bar and pulling up 1" high loops. Using a double headed hook (it helped!), I inserted the hook between the (f & b) bars of the back pannel piece, removing a loop from the other hook and pulling it through the work keeping these loops live, then repeated the process. This brought all the loops from the front pannel over to the back pannel, residing on the back of the work. Then borrowing a page from the knitters, I worked the loops off, interlocking them. The last loop was worked off using the yarn feed and then secured. The result? A clean looking join that involved no sewing.

And how true, how true! We petted the yarns and bought much of it too! We ate great food, and enjoyed each other's company. And we received some great news too: Chava accepted a position with the Feza company -- and, remember all my whining about many yarn shops closing in Connecticut for the past two years? -- FEZA has decided to open a warehouse and office in Monroe! How wonderful! :)
