I had a read through before, definitely found some handy hints that I look forward to trying.
If I can make one suggestion, (luckily I lean towards peach kits) but in your descriptions of each ebook.... perhaps mention if a certain ebook is geared towards a certain coloured raw doll kit? Just so the buyer is aware that a kit they may already have isn't suitable for the techniques explained in that particular ebook; prior to purchase.
If that's not possible, maybe have a thread posted here and list each ebook and which colour kit it's aimed for?
But as I said, looking forward to using it as a reference; and have no doubt I'll be purchasing more.
