You can browse through some antique patterns
here. It's kind of annoying though because you have to open the PDF to see inside.You can do ctrl+f and type keywords though so you can find one with at least some edgings in it.I found a really nice hankie edging for a new lamp that way

I would try a library near you too.They tend to have older books with fancy edgings on them and they're easier to see than the scanned pdf.
