A rust coloured abstract

This week's theme, set by our regular host Ingeborg, is 'Rusty'.  Unfortunately I couldn't find any real rust so I have gone for a shot of my birthday balloons, which after a bit of faffing, have taken on vaguely rusty hues - I hope!
This is Thursday's entry, although of course it is now Friday, but at least I'm back to posting the day after and all photos are always taken .on the day'.
