As the title suggets - I've been given a spare mat for my car - usual black carpet-like stuff, obviously synthetic but not sure what but it's got a hole in it where the heel rests. I've got a bit of old rubber mat that I'd like to stick over the hole but can't find any advice on how to stick it on (plenty of people who've tried double-sided tape & failed!) So I wondered if anybody on here had managed to do this and, if so, what method they used.
