Pleated Christmas hearts

[citation needed] The oldest known guide to making pleated Christmas hearts is found in an 1871 edition of the Danish journal Nordisk Husflidstidende.

[2] The oldest pleated Christmas heart (from 1873) is preserved at the National Museum of Norway, in Oslo.

The oldest depiction of a Christmas tree decorated with pleated hearts dates from 1901 from the Danish manor house Søllestedgaard.

[2] That same year, the pleated heart motif was used by Swedish artist Carl Larsson in the lithograph Brita as Idun.

[3] It is believed that Danish kindergartens from around 1910 started spreading the use of the pleated Christmas hearts, which were made from glossy paper in order to enhance the children's creative abilities, patience, and fine motor skills.
