I absolutley loved the kit from cheeky wipes.  Good on another WAHM for doing something creative.
I actually ended up buying another dozen off the same website so they all look the same with green edging.  I am a bit pedantic like that
 
 
I would say that 18 are plenty though cause my wee girl is only pooing once every 8-10 days at the moment.  You use less with cloth wipes though as they do a better clean up job.  Having 30 means that I only have to do a wash of them every 3-4 days though.  I have a little rubbish bin full of napisan(with a lid) to soak them in beside the change table in the meantime.
