style board: framing and matting selection

I didn't have time for a full Style Board today, busy with client stuff; which included getting a couple things framed this morning for the Norwegian bookcase wall.

#2 White Metal Frame with India Mat

#3 White Metal Frame with Dawn Gray Mat

#4 White Metal Frame with Photo Gray Mat

#5 Gunmetal Metal Frame with India Mat

#6 Gunmetal Metal Frame with French Blue Mat

#7 Gunmetal Metal Frame with Dawn Gray Mat

#8 Gunmetal Metal Frame with Arctic White and India Mat

#9 Same as above, reversed

#10 Shiny Silver Frame with Granite Mat

#11 Shiny Silver Frame with Powder Blue Mat

#12 Shiny Silver Frame with Bamboo Mat

#13 White Metal Frame with Dust Mat
