Must admit i'm the same with all the "FREE" rubbish that gets stuck on the mags and weeklies apart from the Licence wallet from Anglers Mail (original 1 about 5 years ago) and a couple of disgorger's.
Everything else gets put into a box and when there is a fair bit i then pass it all on to any youngsters that i know or see fishing that can get some use out of it.
Mind you some of the spools of line have come in useful for the following things :
Lining the top of my fence to stop Cats & Birds getting in the garden.
Invisible card lines around the front room (stay up all year).
But most important is for sewing up any small tears or rips in my nets.
I tried out some stuff that came with some magazine or other.
It was light match fishing type stuff and I planned to use it on the canal.
Well, It lasted all of 2 hours on the spool. Memory of an elephant and
kinked if you gave it a hard stare!
