Felt landscapes incorporating silk velvet and a question about signing your textile art

Yesterday I finished felting a series of felt landscapes which I am hoping will be selected for inclusion in the Blueprint Christmas Exhibition, fingers crossed please!  It was one of those days when everything seems to go right on the felting side of things, the velvet crinkles wonderfully when felted with the short fibred merino and the simple white frames and off white mount show off the landscapes just to my liking.  Of course that doesn’t mean the people curating the exhibition will feel the same but at least I am happy with what I produced.  My new lables also came in handy as I was able to attach one to the back of each piece of felt, that leads me to the question, what is the best way to sign a framed piece of textile art?  Any suggestions eagerly awaited!
