This is something I've been meaning to make for ages (and a girl needs a break from applique occasionally!!)
It is basically a rectangular bag, divided into two pockets and attached to the bunkbed rails with buttons on straps. This is actually the first time I did buttonholes on my sewing machine. Don't know why I thought it might be difficult...
But anyway, now Poppy has a little bunkbed bag, perfect for a bunny and and a book :)
