Yarns in the keyring are dyed with Woad, Lime, Ground Elder, Purging Buckthorn and Walnut. 
 
Thrums are the ends of the warp that come up behind the heddles when the weave is finished. Rather than waste all the ends they can be remade into chunky yarns, or these fun keyrings. 
 
Mounted on a heavy brass finding.
 
Dyed Ryeland yarns, from the Wederdena Ryelands who live in Suffolk
