Small repair kit - consumable materials?

We all have broad ideas about what tools we'd put into small tool kits for general day to day repair jobs. But I'm increasingly trying to optimise the consumables that go in such kits. Currently thinking - Electrical tape Duct tape Zip ties Hot glue sticks

What else would you carry to help you bodge a fix on day to day repairs? Imagine the kit all fits within a mid sized tool bag.
