Botanical art exhibition

This comes from UKCPS member, Val Hopkins:

The Gloucestershire Society for Botanical Illustration will be staging its Annual Exhibition at the Nature in Art Museum at Twigworth, near Gloucester, from March 26th - April 7th, 2013.

Quite a few of the regular contributors (myself included) use coloured pencils. We have no selection (other than availability of space and copyright checks) as we like to encourage beginners. The contents, therefore, range from the professional to the less accomplished. Nevertheless, people tell us the standard is still very high indeed.
Thanks,
Val
