Get an old plain shirt you don't wear anymore and lay it out on a flat surface.

Simply cut a slit about one inch away from the seam of the sleeve on both sides.

Continue cutting from one slit to another by cutting near the collar line for an elegant off shoulder look to be paired with a tank top.

Fold the back of the shirt in half and cut straight lines about a width of a finger apart from each other. Cut it as long as you desire :)

Stretch and pull the strips you made so they curl up a bit.

Once you are done you can cut the lower hem off if you wish.
You can do the same to the hems of the sleeves.

You can leave it all as it is or you can weave it to make some cool designs.

Take the second string (purple) and pull it up from BEHIND the first string (green).

Pull the purple string down IN FRONT of the green string so it makes a loop like image.

Now you take your third string (torquise) and pretty much do the exact same thing as before. Pull it up BEHIND the higher string (purple in this case) and pull down IN FRONT of the purple string creating another loop.

Continue this step until you reach the very last string.

When you are done it should look something like this with one last loop hanging at the end.

Cut the loop in half and tie it to the strips.

And voilà! You have cut up your boring tshirt and turned it into something more fun to wear :)
