Boring "labels" on your letters? .. Single use only?? Recycle them is what I do!!

It's quite difficult to find stamps that are predominently white so I've been hoarding these rather boring "labels" which the Post Office put on Special Delivery envelopes in anticipation that they might come in useful sometime ....

 "Single Use Only" is printed in the bottom right hand corner, but I've managed to recycle them effectively I hope,  into the sails of my latest boat.


Almost finished .. just a few  details  to add, including a crew and a flag to hoist!
