I think you should try the plyban fabric, it works great and very easy to clean and sanitize beween makes.
Regarding blue cheese, it really depends on what type of blue are you trying to make\recreat. Stiltons use bottomless cylindrical tall molds while gorganzola\rouqfort are more round and can be made with any plain mould which is tall enough so you dont get a flat disc after draining, even a basket mould if you dont mind the imprint in rindless blues.
