I sent that link, Clueless, because in the photo the paper pots are obviously damp and she wrote "Surely they'll fall apart, I thought, and can't possibly be worth the bother. How wrong I was", which I thought gave hope.
I have done it with loo rolls, but I put them in a deepish tray and infilled wherever possible around the pots with compost so they were sitting in compost and I watered top and bottom so it was all damp (sweet peas). I sowed directly into the loo roll pots. I did it like that because the first time I did it I was so worried they would disintegrate that I didn't water enough and they didn't grow properly. Must have been more sparsely than Sybille above! I planted the loo rolls as well.
