When I initially wrote this the exhibit wasn’t due to go up until the weekend and I was in the throes of planning and packing up paintings, hoping the walls would look something like this!
My plan for the Britannia Gallery started with a scaled painting featuring the extraordinary turquoise waters of Englishman River Falls and Little Qualicum Falls on Vancouver Island. 
A reconnoiter of the gallery space revealed that the long narrow painting (11″ x 48″) invaded the seating space. When I removed it and re-spaced the other three paintings I liked it so much better that this became my new plan. Bonus: one less painting to hang!
Britannia wall with a ‘Topographical’ Flint from Denmark, plus Botanical Beach and the 3 Pools at Little Qualicum Falls on Vancouver Island.
Wall with European flints plus a few pebbles/rocks from home. 
Wall with Okanogan Desert Rock & Sage together with a mix of ‘Portraits of Pebbles‘ and the Rock Formation at Point No Point on Vancouver Island. 
Then there’s the 6 foot long display case, and I’m still wrestling with that, especially the visible from both sides part. I expect it will be mostly photos of the inspiration for these paintings.
More of Frank’s Photo Challenge: Rectangles (or in my case: Arranging Rectangles).
