The bed is the focal point of a bedroom and an easy way to create a fairy theme, so go for fairy sheets, pillows, blankets or comforters.
Colder Months: A fairy blanket or comforter is an essential both for warmth and decor. You can save money though if you mix your fairy blanket or comforter with matching, plain colored sheets. Sheets will not be seen at this time of year so they don't really need to special fairy sheets.
Warmer Months: Fairy sheets are best for the warmer months when they won't be covered with another layer of bedding. (Although if you want to save money you can just buy the essential fairy blanket or comforter. You can always make the bed with the fairy blanket or comforter during the warmer months for decor and take it off at night for sleeping.)
