This is a window valance purchased at a now defunct Dutch store. After a kitchen remodel, I would love to find more like it, but have no idea where to start---I don't even know what the pattern is!!! Any help would be greatly appreciated. Thanks.
I started with a Google search for "lace curtain valances." Looking at "images" for some ideas.
Next search "Dutch lace curtain valances," both web and images searches.
There are many auction/buy sites showing new and vintage lace curtains and valances.
Etsy, Ebay, TIAS (the internet antique shop), and Ruby Lane are some I have enjoyed. I am sure there are more.
There are also many internet stores showing new laceware that mimic the older patterns.
If not the exact match, I feel confident that with lots of searching you will find something you like.
