I’ve had this on the go for some time, waiting for hardware in the post and then needing something else and waiting for that. Maybe three times and I still need longer rivets to put the bottom thingys on. It’s made from a big canvas work tapestry found at the op shop, some roll-up plastic cutting boards for stiffening inside the base... which I kept not buying because they were too much money (I want to use what I have if I can, or make do if I can). Very strangely, one morning walking to the train station, I found three scattered on the road. True story. Lining is stuff-sack scraps from camping days. Washable, nylon. Because bags get disgusting. And a couple of really old stash (possibly Mum’s or even Grandma’s stash) zippers.
I need a bag I can sling over my shoulder or use with smaller handles. I bought a gorgeous camel hide back pack but it’s a pest to take it off every time you want something. So this has detachable handles. I can roll up the spare/s and put them in the inside pocket.
