one thing that works (as I am an expert in leaving tissues in the wash) id putting them in a tumble dryer. The tissue comes off and sticks to the filter which you can remove.
You may have to do this a couple of times, and then you can go over with some selotape wrapped around hand to get off those stubbon bits.
Lint roll is good- i got one last week as i always find that my fluffy carpet threads come off on my black trousers. Its about £3 from tesco (like a curtain roller with paper on it which you peel off and it reveals a sticky surface) and you just roll the sticky stuff up and down the clothes til its all off. takes about 2 minutes and doesnt leave any marks on your clothes either! x
