Small rips and tears
Small tears, punctures and rips in either tent fabric or groundsheets can be fixed temporarily with 'gaffer' tape.
Self-adhesive tent patches are available in assorted fabrics and colours from the manufacturer and most better tents will contain a little piece of the tent’s fabric for more permanent patching.
The secret of a neat temporary repair, either with tape or a proper self-adhesive patch, is to make sure the area round the tear or hole is clean and dry. Then get somebody inside the tent to hold a solid flat object (a chopping board or book both work well) against the fabric so you have something firm to push against to get the tape or patch to stick flat and firm without creases or bubbles.
Finally give the patch and the area around it a good spray of reproofer to keep your tent waterproof for the rest of your holiday.
It's always a good idea to have an emergency repair kit for your tent
