[HNW] 18th century sprang?

[Kathryn Newell]

I was visiting a friend a couple of weekensd ago. We were looking at some of 
her books of 18th century costuming. She showed me a page showing a photo of 
a pair of what looked like 18th century netted long fingerless mitts. The 
caption said sprang.

Say what?  Sprang that late?

My understanding is that sprang is a twined work -- no knots. How do you 
work the fingerless fingers part? This really boggles my  mind.  Somebody 
enlighten me, please!
