I have just been to see a pregnant lady who is finding out about cloth and she mentioned a trial laundry service. I immediately said I wouldn't recommend it as they use prefolds but she showed me a leaflet and Cotton Tails now do a variety of fitted nappies and some decent wraps. I was very impressed.
They do a 2 week trial for £25 which gives you up to 21 nappies, you can choosed from Motherease onesize, cotton Tots, Bamboozles, Fluffles, prefolds and nappy nations and 7 wraps including Motherease Rikki, Airflow, Tots wraps and some others.
I was quite impressed and told her to go for it, at least it gives you a fairly good idea of the shape and size of your baby before buying more.
