I wanted to make it totally from reclaimed t-shirts, as they are easy to cut, easy to prod, and feel lovely under the toes when you stand on the rug :)
I chose pink colours, as this was a gift for my sister, and I actually started with three t-shirts she had given me to chop up, although she didn't realise that I would be starting a rug for her out of them.
In the end it took 30 t-shirts to complete, I trailed the charity shops and begged them from friends and neighbours. There is even a starry patterned nighty in there!!!
A regular style t-shirt (Short sleeved) takes around half an hour to chop up into pieces, then about an hour to prod all the pieces into the hessian, and it makes about 1-2" in rug!! So you can imagine a good few hours went into this project.
The rug is around a meter long by half a meter wide.
