I bought some Male to Male flexible cables for my first arduino projects but I can't find a proper way to store them. They are in many lenghts and it is very difficult to figure out which one do I need every time I use them. If someone has a way to organize them I would be very thankful.
Get a flat box from Really Useful Boxes. I have a bunch stacked up on shelf over my workbench.
Staples, OfficeMax have them.
The 4 Liter and 9 Liter sizes are good.
First thing to do is grade them into common lengths. Then bundle common lengths together (but not with elastic bands ) using twist ties as used for kitchen bags. Then place in suitable sized flat plastic container with snap-on lid.
If you make your own leads use a colour coding system for each common length. Use the same colour coding as resistors to assist with remembering then; so shortest lead is brown (1), then red (2) and finishing with black (10) Yes I know black is "0" but a lead of zero length isn't going to be much use !
I use an old wooden wine box and throw them all in there (male/male, male/female, loose and ribbon). A bit messy but I don't have too many so that's OK for now.
For the typical short jumpers, both male-to-male and male-to-female, I use a couple of small open-topped trays, (originally containing individually-wrapped cheese slices), on the workbench for easy access. One sits inside the other to save space when I'm not using them.
I only have a few in those trays, and keep a bulk number still in 'ribbon' form in "Snap-Lock" plastic bags thrown in a cardboard box with other MISC bits and pieces.
