Last year was my first year of seed saving Mick and exactly as Telboy and Fork said is the way I did it, the longest beans are normally the least best tasty so leave the bigger ones on and you get more seeds in them, leave on as long as possible then dry, paper bag and I put them in a drawer, in fact I have just repeated what both of them have said but I can't be bothered to delete. Happy seed saving. ;D ;D ;D ;D ;D
