I love these things, but they seem so pricey for elastic and cardboard. For anyone not familiar, it is basically a firm piece of cardboard covered with long pieces of elastic which are woven together. You stretch out the elastic to hold your phone, cables, wallet, glasses, whatever. This is a medium one, from ebay, using search "grid-it." $14 including postage for basically a piece of cardboard and some elastic.
This is how one guy uses it to organise his bag. I can see so many uses for it. School bags, handbags, storing cords like HDMI/audio cables by the TV, laptop bags. It would make it so easy to pack adapters and cables in a suitcase for travel, and everything is clearly visible. There are multiple sizes available, but I think the medium or large one would be most handy.
I've seen DIY instructions on youtube, but don't have the time or the skill to make one. I don't know if my google-fu is weak, but I can't find an el cheapo knock-off or a bargain price for this. I've searched the usual meritline, DX, tinydeal, and even AliExpress, but ebay seems to be the cheapest.
Hope someone can help!
