I'm very new to this group, but I have been studying Filet Lacis for awhile...though have not attempted to try the old, beautiful art myself. After enlarging a portion of this glorious piece and comparing it to other Filet Lacis, I have concluded that it is indeed Filet Lacis AND Irish Crochet Panels. The hemming along the side is typical AND also serves a purpose for repair, to keep the piece from fraying any further. As you can see the huge enlargement (right) of the section above...it is identical to the smaller insert (left) below. I hope that helps to clear it up that it is NOT filet crochet. Please forgive my intrusion, but this one has really been bugging me. Have a fabulous day and happy "lacing". ;-)
Just one of many places to look up this no longer used, but still lovely style of lacing.
Yes - it is a net, or "laci" work. And seen enlarged, not filet. Thanks for the pics.
