I take duck tape and wrap it around a popsicle stick. You can do two colours on a stick and it's a lot lighter and less bulky than the roll of duck tape. I carry it mostly to make small repairs on a cracked box or pouch.

....I had been thinking the same basic thing.......

Except I don't even use the popsicle stick....I just start with a 1/16th inch fold-over onto itself.
