I took a piece of lace and laid it atop the shirt to figure out where I wanted the scalloped edge to fall.
I pinned under just a bit of the lace along the edge of the neck band and stitched it down , then trimmed away the excess lace close to the stitches.
Working my way around the lace piece, from the shoulder seams to the armholes, I pinned under the edge of the lace and stitched it down, close to the existing seams, one section at a time.
Finally, I sewed down the scalloped edge, very carefully, then trimmed out the part of the t-shirt that was inside the seams very, very carefully. Here's how it turned out.
And here's the close-up.
I love how it looks, and I hope it will be nice and cool when the weather turns hot. I wore it here with a strapless bra, but I may need to buy a regular one in a cute blue color to wear with this shirt.
Thanks for reading!
