Some old fabric from a while ago that my dad's cousin gave me because she used to sew and never used it.
Something I thrifted thinking it was a shirt but it ended up being something else completely that I still can't figure out what.
Lay the fabric out and iron it.
Trace the wrap chest pieces and back and front pieces.
Cut them out.
Hem the side of the chest pieces towards the inside.
Attatch the chest pieces to the top of the front piece.
This is the previous step done.
Attach the sides the front and back pieces together.
This is the previous step done.
Measure and cut out the fabric for the straps.
Fold the bias tape along the back and armpits of the shirt.
This is the previous step done.
Sew the straps to the back of the tank top and the you're done!
