When I went to buy a canvas to stretch it around, I couldn't find one the right size, so I took myself off to Mitre 10 to buy some wood and screws and built a simple frame to stretch the tea towel over. In the wood section I met a woman who was looking for wood to anchor the roman blinds she was sewing to her window frames. Eventually a nice young man came and helped us, we both looked pretty bewildered! (Though not as confused as the screws section made me. Why are there so many different types?!)
I used little tacks to secure the tea towel to the back of the frame, and neatly mitred the corners. I had to undo the side hems to make it fit, but I can easily sew them back up if I decide to use it for it's original purpose.
After putting several nails into the wall to try and get it to hang straight (note: spirit level is your friend) I wasn't really feeling the love. But I really do like it hanging up there on my wall!
