What to do with an empty vodka bottle?

I sit next to the spirits team at work. (For those of you born in the last 70 years, "spirits" is another word for "liquor"). One of their suppliers sent them 40 empty bottles of vodka last week. Yes, EMPTY bottles. (Pointless. Complete waste of postage. Utter waste of money). The spirits buyers were therefore giving away their empty bottles. I took one of the empty (shutter) bottles and challenged myself to use it for a kick-ass arts & crafts project!

I therefore give you... The Valentine's Day Advent Calendar! (Forgive me, Lord, for I have sinned). This beautiful bottle is filled with EXACTLY enough Valentine's-themed M&M candies for me & Mr. Handsome to each have one each morning until Valentine's Day. Let the official countdown for the next exciting holiday BEGIN!
