Ive been following the 'pre srtetching strings thread' and its brought to mind some thing i keep meaning to investigate. i don't change my srings that often but i always keep hold of the old ones and stick them in a draw . when they have been there long enough to form one chunck, i then dispose of them (guitily :( ).Some enterpising body out there must have some ideas as to how to make use of these things , in say, projects for kids etc? With or without the use of a dremel!(see my bottlneck thread )
