For the lace, I lay the lace on the skirt, straight stitch each side, turn over, cut the material down the center, open each side and iron flat, on top, I zigzag where the fold is about 1/8th in over on the material side, this helps prevert the material from unraveling, and stabilizes the seam, which with voile, you really need it.
I made the dress out of Voile, which is very sheer and of loose weave, I don't normally stabilize buttons on a dress, cause I usually use more sturdy material , so I didn't think about stabilizing the buttons, oops. So I dug put some linen, cut 1/2 in squares out, then I needed to finish off the edges, they were too small for serging, so I used frey check. I used a pin to hold them, worked perfect.
More pix of details, the skirt has 3 sets of 6 pintucks. 1 puffing strip, and one lace strip, I didn't originally plan on putting riffon in the lace, but someone suggested I "bring" some pink into the skirt, it can be removed or use white instead.

Close-up of waist, I used the fabric, folded it in half, used a shell stitch from my machine to make the waist trim.
