About 3 years ago I made 3 of these Amy Butler Cabo Halters in a row (one of the original posts here). They're quick, easy and don't require major yardage...yay!!! This one I made out of a curtain panel that I got from Target. It's a really light weight fabric and is fully lined with an invisible zipper. It's still in the 90s down here so it's perfect for the end of summer heat (which as I'm writing this I realize is ironic since I'm wearing jeans in these pictures).
I'd definitely make this pattern again but I'd stitch the front pieces together or tack them down from the inside to keep things from gaping. It would also be easy to convert the halter into a tank by stitching the ties down on the back. Now I just need to dig out the other versions that I made and wear them too!
