What next?

I am trying to work out what to work on next at the moment. I have several very pressing projects on the go but I'm not sure which to go with. My priority has to be to find something that will bring in some money, I can't keep going on the way that I am. I am currently working on a book idea, a piece that I hope to get into a magazine, some fine art pieces, a new work to be sold in chart form and the knot garden pieces. 
I feel like I have a really good idea for a book that will fit well with the mood of the time but this has to be a long term project, there's no way that it will bring in any money in the near future as I have a lot of work to do and then there is no guarantee that I can find a publisher.
The magazine piece is a more likely way to make a bit of income but again, there is no guarantee of take up, the pay is very low and it takes quite a long time.
I am really keen on the idea of working on fine art pieces right now, of course I can't guarantee that they'll sell and they can't be cheap given the amount of work that goes into them. I would love to do some commissions. I would love to do an exhibition. It will take a lot of work though and if I am not constantly releasing new works will people stop looking?
I have designed a lovely new piece that I want to sew as my next 'chart release' this would be the quickest thing to work on but chart sales are too low, I need to take some risks and try and find something that does stand a chance of selling. I need to sell 10 charts a day to make a living, I don't sell anywhere near that many.
The Knot Garden series was a very big hit at my recent demo sessions. I have completed 2 of 4 and I am about 1/4 of the way through no.3. My hope is that I can interest English Heritage in them, either as charts, kits, cards, prints or all of the above, again - no guarantees.
So, 5 good ideas, all time consuming, requiring a lot of work and no guarantee of making anything from them. I have tried working with a rotation before, saying on X day I will work on this and on Y I shall work on that, but once I start working on a piece I tend to become absorbed by it. I have a couple of model stitchers helping me out with the book idea but can't afford to pay people to do it. I guess I'll just have to go with what feels right and hope like mad that something works.

Coming soon - PDF Chart option

My website is now back up and running thank goodness. Hopefully that's the last time it'll be down. Over the next few days/weeks I shall be adding PDF sales options to the site. I have always resisted doing these as copyright fraud is such a big problem in this industry but postage has got so expensive now that I have to go with new ways of doing things. Each PDF will be clearly identifiable as to who it was sold to so hopefully that will reduce the problem.
The PDF copies will be 10% off the regular price (and of course minus the postage) The speciality stitch ones will be ready quite quickly as they are already formatted for PDFs so all I need to do is edit the website to show the option. The Cross Stitch ones are not done yet so if there is one that anyone is particularly interested in, please let me know and I'll put it to the top of the list. It'll take me a couple of days to edit the website to put the PDF options on for the speciality stitch charts so please bear with me (or ask me to prioritise a particular one)
