The fabric was purchased in Anders, Besonders, Gut in Pivitsheide (near Detmold/Bielefeld/Köln). We had great fun with the shopkeeper, and she was extremely helpful too.
The polka dot fabric is washable. It's like oil-cloth but not as thick or as shiny.
There's a mobile phone pocket inside and a zippable pocket. The zipped pocket is lined in pink satin, forgot to take a photo.
The side of the bag has rings which will clip onto exhisting hooks on the pram:
Who knows how this bag came together, the bottom corners are crazy!
Considering I had no pattern to make this nappy bag, I am very proud of it. I hope it's new owners will be too. In the post...
