If you have lots of loose threads, then these large thread reels (spools) are the tool you need. In the high-medieval period loose threads could be kept tidy with a thread reel, what nowadays we call a spool or bobbin. They were used throughout Northern Europe by women of all classes as sewing was an extremely important household skill.
Our version is solid wood and comes in two sizes, this listing is for the large version. The grooves along the length help set up the original wind and make them look pretty. They are light weight and small enough to fit into a travelling sewing kit, that you may wish to take to a reenactment or Larping event.
Measurements: L= 4.7 cm
Examples of similar spools have been found in bone and wood from archeological sites like Coppergate (see example below) in York, England and the Mary Rose ship site.
