I made a review of the paper pot making tool I use for my seeds. Deeeeply unflattering angle, but you get the idea!
They perform much better than you would imagine, holding up nicely when waterlogged. I write the name of the plant on the side in permanent marker. Saves that 'ummmm...what was this?!' moment (we all have them).
If you want to try one of these yourself please have a look at my new venture! I have become a Wikaniko distributor, not heard of them? My shop sells all things 'green' and better for the planet (plus some specifically vegan stuff). Amongst them are quite a few innovations for the garden, including the Nether Wallop Trading Company Paper Potter, and also matching oak dibbers and pot brushes. I even bought my tomato seeds from there this year! There is loads of other great stuff too, if you fancy a look http://Greenviolets.wikaniko.com. Please go and have a look around, tell me what you think, highly recommended :)
