Close ups of the three laces.
Top- The Heba Lace
Middle - The Mairi Lace
Bottom - The Kelly Lace
They have a fine cording on the "face" of the lace and no cording on the underside. The Heba & Mairi are a heavier, thicker lace- more suitable for mantilla or single layer styles because of them being one-way laces.
The Kelly , although it is a corded lace it is much finer and softer and can be worn as a two layer veil.
If these laces are used on a two layer traditional veil with a blusher layer, the lace will not show the right ride when the blusher layer is folded back over the face.
This isnt so much of an issue on the Kelly lace as it is alot softer then theother two- so looks good from the underside.
