The use of duct tape suddenly took off a few years ago and wound up to be a sort of art - or craft, if you will. Not to lose out on an opportunity, companies started making it with colors and designs. Thank heavens we can still find plain old gray duct tape that works. Keep some handy to make repairs or for more creative projects. Hem a pair of jeans, cover a splintery rake handle... or close a leaky duct.
