This lace collar is 8 inches deep. It is chemical lace and absolutely elegant. Yes it needs a bit of repair so unless you are expert lacemaker you should consider this as craft material.
Most of the damage is merely missing connecting stitches and it looks like the breaks at the neck edge were deliberate to make it fit a garment. The measurements are 8 inches deep, 18 inches at the inside neck edge, and 46 inches at the bottom edge. The color is just a shade off white leaning toward the cream family. Simply gorgeous whether you are a craft person wanting it for embellishments or plan to wear it. White on white would be very effective.
