I've bought the ones from Ebay before when Katie was in size 1 and small nappies. The ones I had wouldn't really be big enough to cover her large nappies though. I like Wee Notions fleece and minkee liners. I prefer dark/patterned fleece as it doesn't stain. You could just buy a cheap fleece blanket and cut it up to the size you want too, fleece doesn't fray so no sewing required.
