Early filet lace designs

I’m hoping to spend some time over the Christmas break reading more about the history of filet lace and some of the early designs. I’ll be starting with Pauline Knight’s two books which contain a lot of historical information. I’ve only dipped into them before, mainly to find out how to produce the net background required for filet lace and to learn how to work the stitches. I have to confess that despite learning how to make the net I used finer meshed machine-made net to work the stitches. One of the things I’m interested in is whether there are albums of design sources for these early pieces of filet and if so whether machine curtain lace designers would have had access to them when producing their designs. Curtain lace and filet lace are both based on square grids and it would make sense for the later designers to use or adapt the patterns of the early ones.
