Baking tube squeezy-thing

What’s the best way (origami style) to make one of those cone shaped-ish pipette thingies that squeeze out melted chocolate etc. onto cakes, made out of baking paper? I made one recently and let’s say it was a disaster lol.

Ideally I’m looking for step-by-step instructions.

Thanks. :smiley:
