If Winry has spoken to you in the past, you're probably getting at least cookies.
Cho Hakkai: Two pies (because he's got a friend who really likes food.) Probably cookies, too. And a small leather journal to write his travel notes in.
Denzel Crocker: A silver fairy charm and a pie.
Willow Rosenberg: A pair of silver earrings with malachite drops. And a pie.
Soma Cruz: A pie.
Van Hohenheim: A pie, cookies, and a picture she has of Trisha, Edward and Alphonse Elric.
Charlotte: A fly pie. Yeah. We're not going into how she made that, 'kay?
Harry Potter: The Boy's Book of Adventure and a toy knight on horseback. And a pie.
Edward Elric: A deep dish apple pie, cookies, this
vest and this
shirt.
Alphonse Elric: A kitten kit, even though he can't have a kitten yet. Collar, bowl, catnip, bell, toys...and some good polishing compound.
Ichigo Kurosaki (Secret Santa gift): Two shirts, one a black button down shirt with green flames licking up the sleeves and the hem and a t-shirt in dark red with a slightly darker red skull and crossbones on it; as well as some bite sized chocolate cookies.
Yoruichi: Very detailed plans for a motorcycle. As well as cookies.
Naoto Shirogane: A puppy kit (leash, collar, bowl, food) and, with Edward Elric and Alphonse Elric, a pair of puppies.
Kurt Hummel: A pie and a hand cast bracelet with matching cuff links.
Lt. Montgomery Scott: A book on automail engineering written by Pinako Rockbell. And cookies.
Blaine Anderson: Cookies and hand cast cuff links.
Tommy Gavin: Two pies. Delivered by Xion.
Rapunzel: A pie and cookies, and a hand cast bangle bracelet.
Merlin: Two pies (to share with Gaius and Gwen), cookies and a hand-cast wrist cuff.
Captain Brannigan: A box of cookies. Mostly because she figures no one else will give him anything, and she feels kind of bad about that.
Greed: Cookies, a pie, and a girly calendar for his bar. Note: Neither Naoto nor Winry is included in this calendar. There is also a written apology to Mr. Greed for her actions earlier this year and hopes that they can remain friends.
Claire Bennet: Assorted cookies.
I think that's everyone....
