Thanks to Laurie of Indulge Your Shelf, I found out about this great website.
There are several categories which I think my blog could be listed under and I'm now listed under (Painting, Illustration &) Mixed Media. I am also going to join the Arts & Crafts category to get my blog out there. A great way to find new blogging friends!
The guidebook also has fantastic resources with a Giveaway Section, Blog Events & Linky Parties, etc., etc. There is also a very useful Help Desk. There is so much to read on there, I have only skimmed through it for now but will go back and have a proper look. Until 31st August, there is a special offer on - blog about the Guidebook and send the link to them and you may get a FREE blog button listing with them! Great stuff.
