Have just started using my reusable nappies for my dd. 7 years ago i used them with my ds and just used normal wipes. Have been using cotton wool so far for nappy changing, unless out and about. Want to use reusable ones now. What are they made of? Can i reproduce my own? (am on very tight budget this time). Do you wet them when you're ready to use them? DO you just add water or somethihng else too? Do you just add to your nappy bucket after use and wash with the nappies? TIA
