One of the swaps I joined in March was to make a postcard using a technique specified by the swap organiser. On this occasion the technique involved painting over a background of cardboard shapes and crinkled tissue paper.
Check out Therese Urbanska's blog - she has some pretty Christmas decorations made using this technique.
Needless to say I launched in with no proper forethought - and glued a bird shape to my postcard and covered it with crumpled tissue no problem. Then I got to thinking about the painting but I really should have done that first.
Me and my rules - I decided I'd have to use brown (because my bird is a sparrow) so what with my lack of painting skills the end result is not exactly eye catching. Oh well, live and learn.
