After seeing the red trench I made for my niece, my sister requested one of her own. At first she wanted a red one as well, but in the end she opted for a plain black one. I was a bit slack in getting started on this project so it has sort of become an early birthday present for her, which actually works out well as I wasn't quite sure what to get for her anyway! The weather is starting to warm up again now, so I hope she still gets some wear out of it.
My sister is tiny and will get away with the size 12. If I was a couple of dress sizes smaller, I'd also be making one for myself.
