I found the shop stacked floor to ceiling with bolts of fabric.
Here's the latest addition to The Stash.
Cotton dirndl fabric at a great price.
This would cost three or four times as much in other shops.
They also had some stretch laces I thought were interesting.
I bought a meter of each to go towards future bra making projects. At some point I need to make something other than 19th century undergarments.
On the off chance someone stumbles across this post and wants to find the place, it's located here:
The shop is called Textil Müller. They have a website.
