My thoughts are totally turned toward summer and so my scrapping has been inspired by photos from summers past.
To make the bottle appear transparent and, in my opinion, more realistic, I selected the part of the sea grass that was behind the bottle, copied it onto its own layer, moved it in front of the bottle and lowered the opacity to 15%.
Here's how I copied the precise selection:
-I selected the bottle shape by CTRL+click the thumbnail in the layers palette.
-Then I made sure the sea grass layer was active and hit CTRL+C (this copies only the part of the sea grass within the bottle shape) then CTRL+V (this pastes that selection into a new layer).
-Then I pulled that layer over my bottle layer and aligned it precisely.
