I was in two minds whether to post this ... the watercolours went very wrong so I covered it all with acrylic, and I used a plastic folder for stencils, which didn't work very well!  The best attempt was the white bars.  I will get the recommended type of paper - it's Mylar paper here in UK.  Then I didn't like my black lines on top (with non-dominant hand) so I covered awkward-feeling bits with gold dots, which I did like.   So the result is rather busy.  Need to practise 'less is more'.  Thank you again, Denise - all great fun!
