I had a little mini house warming at the weekend and made some Mexican food for my guests. As some of my guests have specific dietary requirements i thought id make some food id flags to make sure there was no confusion. They are simply washi tape wrapped around a cocktail stick with the little triangle cut out of the end to make it more flag like. I wrote on them in silver pen and popped them in their corresponding dishes. Super easy and saved any potential confusion.
[sorry for the terrible photo, i planned to take better ones when they were actually in place but forgot until everything was pretty much eaten and looked like swarm of locusts had attacked so it wasnt looking very photogenic...]
