New Pattern: Pie Crust, Progress and Milestones

So Pie Crust is finally out for download on Ravelry. When I have time to wrestle Blogger to the ground I will update the side bar with the download links and so on but it's in at least two sizes - using different weights of yarn and fewer or more repeats of the lace border and the ruffled edge.

Whilst Pie Crust has been being tested and edited I have been busy doing other things like practising my stranded colourwork by knitting Endpaper Mitts (Eunny Jang)

And contemplating my next project...

As it stands I have 99 projects loaded onto Ravelry, including my two WIPs, so I'm wondering what I should do for my 100th project as it feels like it should be a milestone.

• Should it be challenging or easily achieved?
• Should it involve new techniques or old comfortable favourites?
• Should it be my own design (I have a couple of shawls, a ruffly scarf, some more colourwork mitts and a colourwork hat lurking in my design book) or should  I use someone else's pattern?

Answers on a postcard please...
