Tea towels often have really nice designs on them and can look good on walls!
Recently I bought one (to use as a tea towel!), but after I washed it, the writing on it started to peel away and look all scratchy. It would have been a waste to throw it out.... so I cut it up and made some pictures out of it!
These frames are from Ikea. Placing the two pictures together makes more of a visual impact, and I liked them so much that I even matched the colour of my office feature wall to the tea towel! (my office is in the background of this photo).
