I'm trying to source some large cloth / hemp / yuta or cotton bags in CM. Basically, it needs to be a breathable material as it's for storage. And by "large" I mean that hopefully they can fit a microwave or two, or even bigger (it's not actually for a microwave, just using as an example).

Any ideas where to get those? I've searched around already and no luck. Will Warorot Market have these and if yes, which section?

Thank you in advance!

I'd say that for a very reasonable price just about anyone with a sewing machine would make what you're wanting.
