The Snow Faerie (Taelia) can be found in Terror Mountain, at the Top of the Mountain. See link for direct link. There should be a button to click that says "I have your ingredients!" (if your time hasn't run out). If you have all the items requested, they will be turned in and she will give you your reward).
If you are asking this question because you want to do the snow faerie quest then you will just have to wait for taelia to ask you like all faerie quests
She gives you snow faerie type items like a Snow Faerie Plushie. She may also reward you with an Ice Cream Coupon that can be sold or used at the Happy Valley Ice Cream cart. You'll also get Taelia as a Battledome Challenger, an avatar, and a random snowball. You may also receive Neopoints as part of your prize.
Basically, you just have to wait for a random event if you want a quest from the Air, Battle, Crafting, Dark, Earth, Fire, Light, Water, Space, Fountain, or Queen faeries unless you want to spend neocash. If you are willing to spend Neocash, you can buy a Faerie Quest Fortune Cookie when they are available. They guarantee you one faerie quest a day from any one of the above faeries (except the Crafting Faerie) for a week. It is also worth noting that there are three other special faeries: the Snow Faerie, Jhudora, and Illusen. The Snow Faerie will grant you a quest whenever you visit her on top of Terror Mountain. Jhudora grants a quest every 12 hours if you visit her on her Bluff in Faerieland, so long as you also have not done a quest for Illusen in that time. Likewise, lllusen grants a quest every 12 hours from her Glade in Meridell, as long as you haven't done a quest for Jhudora in that time.
There are two types of faerie quests. First, there are quests that are given to you via Random Events that will pop up on the top of your screen under the main Neopets menu. These are viewable at the link "Faerie Quests Page" below under the Related Links section. You will have an unlimited amount of time. The other type of faerie quest is much easier to access. You can get quests from the Snow Faerie (Taelia), Earth Faerie (Illusen), or the Dark Faerie (Jhudora). Each of the quests is timed, and asks for you to get a random item. These quests are based on points: you earn points when you complete the quest on time, and your points go back to zero when you do not complete them on time. The higher your points, the better you prizes are for completing the quest. There are links to these three faeries in the Related Links section as well. No matter what kind of faerie quest you get or start, they will always ask for you to fetch them an item. Many malls ('Notice Board' link below) have specific shops where you might find items that are often asked for in Faerie Quests.

Solve? You complete a Faerie Quest, or completeanother type of quest (snow faerie, esphagor, Sophie the swamp witch) by doing what the person asks you. Faerie quests are rare, and ask for quite expensive things (most of the time; it depends on what faerie asks you to fetch the item), whilst other quests ask for things in a certain amount of time, you choose who asks you by going to their home, and their rewards are not amazing.
