I only have one PL vase - I just can't find another that is 'the one' at the moment (the others are Greg's post
And at the moment, I have only a small collection of Will's vases (I've kept those that have sentimental value) - I've given many away as presents over the years. I've also given the paperweights away as well, as they are perfect for 'boy presents' as they are quite 'masculine' large and very heavy, really quite sculptural rather than paperweights.
I slightly regret giving away some of the paperweights to be honest, but we are near enough to him for me to find pieces by him round and about, and also to be able to visit to buy new pieces. So I know I will be able to add to my collection.
