??? "Elastic"? I routinely pump uninstalled tubes hugely to find small
air leaks (yes, I know I can use water, but higher pressure and sound
is easier) and I've never, ever, EVER found a tube to stretch beyond
its original size -- and I've owned and used tubes for quite literally
10 years, adding over 2 dozen patches to them. No, your tube won't
stretch and fail to return to its original shape, at least not so that
you will notice.

Secondly, a well applied patch will rip the original rubber before it
will separate, at least from a lightweight tube.

I have plenty of practice: learned to make my own patches out of old
innertube, age 10 or so, from sidewalk bicycle wallahs in New Delhi.
Now, I live in goathead country and patch more in a month than many
patch in several years, buy patches by the box of 100 and rubber glue
in 4 oz bottles from Office Max. Not boasting, just confirming that I
know from patches.
