Bias trim trick for finishing necklines/hems on knit fabrics. (Cutting 1 1/4" strips of knit or woven (I used woven), you first stitch the long raw edge of one strip to the raw edge of the shirt body at neckline or armscye. Then flip, press, fold under the bias strips on the wrong-side of the shirt and triple zigzag-stitch. The result is a lovely, sturdy, and firmly-stretchy trim sure to withstand kid-wear.)
Great summer crochet inspiration and so easy!!! You make 4 granny squares and join them corner to corner! Then you make rows of the granny stitch until you reach the desired length! Finally you make your straps by joining the top corners and voilà!!!
