Hi,
The Sewing bee is filmed at Trinity Buoy Wharf.
https://www.trinitybuoywharf.com/An interesting place to visit, I visited back in 2009 as part of Open House.
You can take the DLR to Canning town and then walk across the river lea on a foot bridge.
It's one of those places I want to revisit now it's developed a bit.
Shared calendar should be up and running now.
Ian
