The brand doesn't matter, only that permanent markers are just way too much fun, and a thousand times more versatile than you would guess. There are so many more uses for Sharpies than drawing a mustache on your passed-out friend, and here are a few to prove it:
This cup and tote bag comes from Etsian Brooke's shop, Brookish. The shop hosts all things Jane Austen and boasts her super cool handwriting, but if you want to test your own hand these projects would be so easy. Plain tote bags go for under $10 in almost every craft store and Sharpies are less than $2, so for under $15 you've got yourself a chic, eco-friendly shopping bag with something to say. Wouldn't it be cute to wrap a gift in one of these with your card written on it? That way they can carry the sentiment with them wherever they go, long after a conventional card has been recycled.
These cups are simple to make, too; just write or draw anything you want, and bake it in a 350 degree oven for half an hour to set in. I might have to start writing mine and my roommate's names on all our cups, so we stop mixing them up all the time. It's a real problem when one roommate likes tap water and hates sparkling, and one loves sparkling and won't drink tap. After ten minutes in room temperature they look the same, and then you've got two very annoyed roommates.
You could even go crazy and use a few different colors for a truly creative dish:
They look like something Anthropology would sell for $40 dollars apiece, right? How awesome would it be to have a kid's party where everyone got to draw on a plate and take home a permanent reminder? And if you get them at the dollar store it's a way more cost effective day than going to Marine World and less germ-infested than Chuck-E-Cheez's.
Or how about this scarf from Hermes?
Sorry I got distracted by the scarf. This is the most beautiful and original piece of fabric I have ever wanted to put around my neck. I want it SO BADLY. But I also think you could look to it as inspiration for your own chic scarf, using just white fabric and a black Sharpie for a neat drawing or sketch to make your outfit truly your own.
Or do you remember that guy famous for drawing a whole wall-to-wall mural in his recreation room with nothing but Sharpies? Beats any wallpaper from Ikea, tell you what.
This is but a taste of the billion projects you can find on the internet involving Sharpies. This is why I think what we really need, as a nation, is a Sharpie Day devoted to crafting with naught but our trusty pens, and maybe some booze. Booze just goes without saying for every holiday.
