All you’ll need for this is an old T-shirt and some scissors. I think this tends to work better with slightly looser fitting T-shirts so just keep that in mind.
1. Cut off the neck collar – don’t worry about exactly where you cut this we’ll adjust the neck line later
2. Cut off the sleeve, start a couple of inches below the bottom seam and curve around to meet the seam on the shoulder.
3. Take the sleeve that you’ve just cut off and lay it over the other sleeve so you can use it as a stencil when cutting off the second sleeve. This way it will all be symmetrical.
4. Flip your T shirt over and cut across the back of the shirt and up to neck. You want to make this a racer back, its up to you how skinny the middle section is and how deep you want the back to go. Again take the section you have cut out and lay it on the other side as a stencil to keep everything even.
5. Now choose your neckline. Here I went for a simple V neck. You could also do a deep V or a crew cut. Neaten up around the armpits and around the back of the neck as well.
6. Not cut off the stitching along the bottom of the shirt.
7. Stretch this out so it makes a nice rope.
8. Starting at the bottom of the racer back tie the rope in a double not around the skinny part. How far down the skinny part that you tie the know will affect how deep the back of your tank is.
9. Wind the rope around the skinny part up to the top and tie a double knot. Again, how far up you go will affect the look of the shirt. If you want a long rope in the back start as low as possible and end as high as possible. You could also just tie the rope around a small section if you prefer. Once done, snip off the ends of the double knots to neaten it up.
10. Choose what you want to do with the bottom of the shirt. Here I cut it so it is higher at the sides and curves lower in the middle like a baseball T. You could also go for a high-low look where the front is shorter than the back, a crop top effect or straight across. Neaten up any cuts you’ve made and voila!
