Maybe a bit off-topic, but I'm trying to think of the right search terms either for google or Ebay to see if there are any sort of flat rectangular type holdalls or canvass bags, etc, that might be the right sort of dimensions for what I need.
My stage music stands for the jazz orchestra are made of Correx signboard, in several flat-pack sections. I currently use ReallyUsefulBoxes crates to transport the pieces to gigs, but I'd like to find some sort of bag/holdall in something durable (canvass, that sort of thing).
For example I have a stack of flat pieces which form a block about 630mm x 320mm x 150mm. If there were a bag in which this cuboid block of pieces would fit neatly, with a nice carry handle, it would be less cumbersome. A typical luggage holdall large enough to fit those would be baggy and messy and mostly empty.
If I also had another bag 630mm x 150mm x 150mm, in other words something rather long and thin, perhaps tubular, to hold the smaller parts of the stand assemblies, even better.
Maybe some of you can suggest hobbies or trades that make use of kit bags, tool bags, carry bags that might fit such rectangular demands and perhaps by luck yield something that is almost exactly the right size for me?
