 Leftover and scrap yarn can be made into "scrumbles" that can later be joined together.The name 'scrumbles' was coined by James Walter and Sylvia Cosh during the 1990s and has remained the term since.However Jenny Dowde in her books "Freeform Knitting & Crochet", "Freeformations" and "Surface Work" has coined her own terminology for the "scrumbling" as "fragments"; while Prudence Mapstone calls what are known to others as "scrumbles" "patches".
