Making Jewellery Magazine hit the high street just over a year ago and I think it's probably the best of its kind in the UK at the moment. It covers easy to do 'at home' projects with metal clay, polymer clay, beading, lampwork, as well as more tradtional silversmithing work. Also some pretty good links to jewellery suppliers.
It has a bit of a way to go before it's as good as the American Art Jewelry mag www.artjewelrymag.com but a very good start.
They're also very good at posting projects on their website. Check out www.makingjewellery.com.
I've written 7 jewellery projects for them using metal clay and polymer clay and 2 event reviews .You can see those on my flickr site www.flickr.com/debbiecarltonjewellery with a bit of preview below.
