I have lots of muslins (58 x 58cm) that I got cheap in the M&S sale and I have bought a few Motherease / Popolini wraps, so I hope that will do to begin with. I have lots of cheap facecloths for cloth wipes / for boosting.
I'm thinking of buying some bamboo terries for later on.
I have some of my husband's old cycling tops to cut up and use as liners (athletic wicking jersey, I think / hope!) and when I settle on a size of liner and convince myself that any cheap fleece will do the job, I'm going to cut up a fleece blanket for liners too.
I'm trying to resist the temptation of all the gorgeous fitted nappies (I keep telling myself I don't know what shape / size baby will be yet).
