I found some tank tops on sale at two for the price of one so I bought them. I hand dyed them with blue Rit dye and then combined two to make this cute, ruffled top.
Flamenco Ruffled Tank
I drew lines on the tank to guide my sewing.
I cut up the other tank in strips the same a little wider then the lines I drew so they would overlap a little when I sewed them down. Then I made each ruffle strip about 3 times the length of each line I drew, ruffled them by gathering and sewed them down.
