Someone in our lace group sent us on a side quest of illuminated manuscripts, so I'm just pawing through them while I listen to music.
I stopped here for a close look at the altar fringe (prolly not lace), but I loved the insects in this piece. This illustrator loved them, I think. Are those moths @alexwild ? And a dragonfly?

@mem_somerville Forgot to say, yes I agree with you totally. The illustration because they have to (it needs to be there). The borders are because they want to (fun and enjoyment).
