Cool ways of mending clothes

We are cycling along and it is all lovely and then all of a sudden my son and his bicycle are on big heap on the ground and I'm trying to untangle him and his bike. Then there is a big hole in his new t-shirt that wasn't there 2 seconds earlier.
Recognise the scene?
So I've been making knee patches for my Etsy shop and wrote about it last week here.
And  here is a great tutorial on how to put on the patches and other great tips on mending clothes.

The top one I found at this blog called Refashion Co-op

And this cute on is from Design Mum, nice blog I think. This last one is actually the back of a rug but I would like to use this as an idea for more organic and arty looking knee patches .
