I use white cotton, because its easy to see after a month or so to remove it, but mainly its because thats the only colour I could find at the local shop
Check out the pinned step by step guide to Moss and riccia above for a great method. I have also had a lot of very fast success with attaching Java moss to slate by filling a quarter to half inch of water in a propagator and placing slate in the water with just the top surface breaking the water. I then cover it very thinly in moss and put the clear to p on. It is placed in a bright place (my conservatory), but away from direct sunlight. The moss is usually attached and growing well within two weeks. Christmas moss takes a little longer to attach. I'll upload some step by step pictures when I next do it.
Best wishes.

hi cheap fishing line is the best as you cant see it , you could use flouro carbon line which is invisible under water but is more expensive. regards john
yes! thats exactly why i use cotton, because it will rot away after so long.
but be sure to get real cotton and not that polyester stuff because that won't go away lol
