Have you been thinking of making a beach-cottage dollhouse or a beach-theme diorama? This miniature seagull (1:12 scale) would be so perfect for that! This detailed step-by-step Seagull Tutorial from Lesley Shepherd at About.com suggests using air-dry Delight clay to make the bird because Delight is very lightweight when cured. Birds made with air dry clay can nest in branches or hang on tiny trees without pulling the tree branch down.
Of course, if you prefer, other brands of air-dry clay could be used....or even polymer clay! If miniatures are not your thing. I believe this seagull could be created larger using this same tutorial and still look very real!
Excuse me now, I must go and plan my miniature rustic beach cottage (with some seagulls)! I think I will make it as 3-D wall art instead of a complete house! Still planning........! ;-)
