It is used as a sealant for unwanted open spaces in the hive. Propolis is used for small gaps (approximately or less), while larger spaces are usually filled with beeswax. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures, it becomes hard and brittle. While foraging, worker bees primarily harvest pollen and nectar,
Stitch and glue As such, unlike other construction techniques of the day, which required specialist skills and tools, Stitch and Glue was supposed to put boat-building within the reach of the average public. Although stitch and glue is similar to a traditional form of boatbuilding from northern Europe, particularly Lapland, called "sewn boats", it is not known if Littledyke's development of the stitch and glue methods was influenced by that technique. In the United States stitch and glue boat building was popularized in the mid-1980s largely through Harold "Dynamite" Payson's articles in "WoodenBoat" magazine and books on building "instant boats" designed by Phil
