This years theme has had me rather stumped. I couldn't think of anything that would fit in with current projects without a significant amount of shoe-horning or a merely tenuous link. I therefore began thinking more generally.....
Something ill-advised would likely be considered folly; Therefore I have decided to build a Folly or tower. As it won't be for a specific project and I will likely have no use for afterwards (just like a real Folly!), it will be a fantasy influenced piece. I may subsequently then be able to sell it on to someone for Frostgrave, Warhammer or similar.
The last fantasy building I made was likely more than 20 years ago, but I'm rather looking forward to it (presuming I have enough free time, as I am currently building stuff for someone else which really should take priority)
I don't have a specific design in mind, but it won't be as large (or legendary, or mysterious) as Jimbibblys Wizards Tower

Small blue foam blocks may be involved though...
Good luck to all the other participants and thanks to Vanlak for raising his head above the parapet to run the contest.
