I'm glad to hear that you've welcomed a new hamster and I look forward to hearing about her.
If you're looking for fabric hammocks and shelves then these are my favourite suppliers:
Fuzzbutt Cage Comforts: Fuzzbutt Cage Comforts - Fabulous Furniture for your Fuzzies!
The Homer rage is the perfect size for a hamster.
Dainty Paws: https://www.daintypaws.co.uk/
She'll take custom orders from time to time where you can choose your fabric out of the many she has available and the fleece to go with it.
Cosy beds and Burrows: https://www.cosybedsandburrows.com/c...k-hangers.html
Although they sell more in the way of guinea pig toys, I buy their little fabric shelves to go in my bin cages. The small is perfect for a dwarf hamster and my girls in particular love to sit on their 'chatting' through the mesh.
