I do, usually at home because I always carry a spare tube with me. Once a tube has been patched enough times (more than once and certainly less than, say, seven million times), I cut the part with the valve off and use the rest to wrap the handlebars (underneath the tape), patch things up etc. On rides I carry the very thin, self-adhesive and transparent Topeak patches (for when I get the pleasure of having more than one puncture), which work well but not necessarily for very long, while at home I use proper rubber ones which are much stronger and more durable, but also require glue.
