Last year I noticed that a couple of the corners of the inner compartments are missing, just a big hole. They are at the bottom (on the ground), and usually have a hook for a tent peg to hold the compartment in place.

Can I repair these? If so, where do I start!?

I found a company a while back who repaired a torn inner door in a north face tent. They were in scotland and posted the tent to them, did a great job and were not too expensive cant remember the name etc but still have hone number might be worth a try 08453303140

These guys?

Those people do look good, and if I can't fix it before I go away, then I may well use them when I get back.

I know I've left it to the minute. I need a DIY solution really, as we'll be using it for the Exmoor Explorer in less than 2 weeks.
