Sewing Invisible Seams on Lace

I have just learned how to do one of the prettiest techniques ever - that of joining lace without a seam. The dress my daughter had tried on and loved, had no seams or at least nothing visible. I know you can't "shrink wrap" lace but it fit so perfectly with no apparent seams - what a puzzle! Reading up on it and talking to my friend Mary Ray who at one time made bridal gowns, lead me to this technique. I did a little mock up for some of the parts,  like in the photo below. I started by marking the seams with a pink basting thread.  Resources say to  never use black or any color as lint from the thread is impossible to remove. For easy viewing here, I used black. The seams are marked and a good amount of lace is left for the overlap.
Cut the lace in the overlap area (1-2 inches beyond the seam allowance) following the lines of the cording or applique. Trim one side only in the pair of seams - the side that will go on top.

It will look like this (below).

Overlap the seams by laying one marked thread line over the other - allowing the "pretty cut edge" to be on top. Pin the seam lines together - Pins should be very close together.

Next pin the top layer down, making sure to secure the appliques. Again, use lots of pins.

Set your machine for free motion sewing; thread top and bottom with a clear monofilament or white thread. I did a test for both threads, either works fine, however regular sewing thread is easier for me to manage.
Set the machine for a fairly narrow zigzag stitch and stitch around the edge of appliques the entire length of the seam. This is time consuming; make sure to catch every edge.
Once stitched, flip back the top layer of lace to see the "underlying seam" which will be wide.
Cut away excess - @ 1/2" from the stitching. The photo below has 2 pieces joined together - my family couldn't tell where it had been joined.

The red arrow points to where the 2 pieces of lace have been joined - hard to detect. This is a beautiful technique and perfect for joining lace fabric.
