Melt the white chocolate chips in a microwave-safe bowl until they can be stirred smooth. I microwave in 30 second increments, stirring between each time.
1 12 ounce bag of white chocolate chips
Scoop melted chocolate into a pastry bag with a small round tip. (You can also use a ziploc sandwich bag, just cut the tip off.)
Arrange pretzels in the shape of a tree on a sheet of waxed paper: Place two pretzels with their ends touching to form a tree, then place the third pretzel in the center of your "tree" for the stump.
48 pretzel sticks
Drizzle the melted chocolate over the pretzels to form the tree.
Decorate with sprinkles before the chocolate sets.
