you have ever spent on a nappy? For me probably around the £40 mark for a custom using my own fabric or embroderies. There are some priced nappies out there though - $210 for ONE nappy!! http://www.barerumpsnappies.com/customs/
I've never really got into the WAHM/customs thing. I think the most I've spent on a single nappy is about £17 but it's usually much less than that as I shop around for the best prices, wait for sales or RNW and buy preloved.
