Hello Dawn! have a look at the Newcastle Watercolour Society; it may not be what you're looking for, but there will probably be someone there who can point you in the right direction.They are having an exhibition 29th July - 2nd August, so perhaps you can do some networking!
Contact Ray Shore on 01782 324 468.
I'm not dure how far this is from where you are, but its worth a try.
Also, in the Local Clubs (A - Z Clubs) on the top line of tabs, you'll find 6 Art Clubs in Staffordshire, but they may be too far south for you.
Best wishes and good luck!
