Here's a case where pillowcases really benefit from topstitching. The cat fabric had just a splash of red in it, while both fabrics were predominantly blue. I think red stitching adds a nice touch.
That earlier tea towel is appearing again, also as wrapping for an ornament.
I far prefer to wrap a present in something useful than in wrapping paper, which is such a waste. And lovely fabric is always going to be nicer than wrapping paper.
