I wish I had a photo, but I don't since I don't know what to call it to search for a picture. It's when you pipe realllllly thin teeny little strings all in a row to look almost like a lace edge or little wires. Do you know what I mean? I want to learn how to do that, but I don't even know what it's called.

i think "drop strings" ??

"Bridge Work" maybe? I'll post a pic of an example.... Be right back...

Yah, I think, but not like you normally thing of swags, but instead they are vertical lines.

Also known as Extension Work or Stringwork or Curtaining.

That's it! Thanks! It looks excruciatingly tedious, but it's insanely beautiful!
