Artists & Craftspeople
If you search for a stone memorial for your pet often the sites that pop up are not the actual stonemason or engraver, but other companies that offer a range of memorial products and are the 'middle man' as such.
I have found Spindrift Engravers in Northumberland. Based in Alnwick, they are members of the Guild of Master Craftsmen and can offer a good range of Memorials for the garden.
Shown on the Pet Memorial Plaques and Grave Marker pages are pieces made in black or grey granite.
If you look at the rest of the site you will see that Spindrift also work in sandstone and slate.
They have a variety of text fonts and colours, as well as images such as pawprints.
The best part about liaising directly with the craftsman is that he can create a totally individual piece to your own special requirements.
