Browns Designs for Church Needlework
This is the best resource I have come across for ecclesiastical embroidery designs.
The book dates to the late 1800's and is packed with pages and pages of absolutely wonderful line drawings to use as the base for your needlework.
The official title is “Over 1000 Designs for Church Needlework and All Kinds of Embroideries Used in the Church” which is why everyone calls it “Brown’s Designs”
I am including the book here in 6 pdf files.
