Writing another book

I'm working on a plan for my second book and hoping to get a publisher deal this time so I don't have to worry about printing costs and I can put my feet up a little. I've pretty much put my proposal together but I thought it would be nice to ask for your opinion as to what tutorials you might like to see. Here are a few designs, any favourites?

Also I'm working on a huge order, so if anyone has bought the 6 cavity round moulds I sell (I'm out of stock at the minute) and doesn't want it anymore, I will buy them back! I need at least 2 more!
