Needed: solid-color tank top - cut up each side - cut two panels of lace either 2 in. wide or if you want your top to be bell-shaped (as shown), cut the panels wider at the base and narrower at the top. After the lace is sewn, hem the bottom of the entire tank top.
DIY, no sew triangle tee-shirt *Be careful how far you make the slits in the front. In the back it doesn't matter so much. It was fun making! Great for wearing any day or even cute for over your swimsuit.
