This went very well! Nice.
I started "all blue", too, when I took my first. I've meanwhile tried several colour background, from extremely colourful to two-coloured etc. ... droplet pics are fun!
Oh well, I worked with present wrapping papers... picnic boxes ... towels .... coloured paper ... anything that sprang to mind might make a nice background. ( see_here and here and here and here <- all those are last year's, and here as one example taken this year, I haven't shown any more from this year's series here on TPF, though).
