EMF Camp - Vodka Roulette

Image
I thought I was at the end of the 'things made at EMF camp' but then I remembered I actually cut some stuff for myself while I was at EMF camp. It's probably because I prepared most of the things in advance but they were cut and assembled at EMF camp so that counts right?

I've made flavoured vodkas before by dissolving boiled sweets into vodka and coming up with some pretty tasty flavours. This year I thought I would go one step further, I made 5 sweety flavoured vodkas and 1 nasty flavoured vodka and being a field full of tech geeks I figured they would appreciate a mechanism to automatically select a flavour for them.

MSRaynsford Gift Cards

"Alex Bailey requested a laser cut gift voucher for his dad, Adrian" ;)

So that was basically it, but I realised it was a good idea and agreed to make him a little laser cut item to represent a gift card. This all happened weeks ago but given the recent spate of catapult fiddling you can see how the two get connected. You get some instant gratification in the form of a mini catapult which you can assemble while you wait for me to ship the item you pick from my blog (this includes customised items).

If you would like a giftcard simply copy the file I shared last week, change the wording at the bottom and return it to me

Both giftcards and catapults are available from the same listing
