Run them both concurrently.  One will be ending in Jan and this one is a bi-monthly so it will end in Feb. 

I say let Dan's challenge stand as he described.  It is the perogative of the last winner. 

We did have one not too long ago on abstracts.  AS entered it with an abstract sculpture, if I remember correctly. 

My question is:   Can an older piece in someone's gallery be entered into the competition?  Or, does it have to be a completely new design?
