Ha, if you want white snow scenes I used up all of mine on Ailsa’s Travel Theme: Snowy.
However, here are some white summer flowers that have been apped to bits…
A white flower in Singapore Botanical Garden apped with the Photoshop Express ‘Dream’ look.
A white magnolia edited in the photo app Pixlromatic using one of their many Bokeh overlays.
A branch of white flowers up against an orange wall, texturized in Pixlromatic.
White trumpet vine run through the deliciously creamy ‘Gouache’ of Sketch Guru.
White crocuses lost all their detail when I turned them into watercolours in Waterlogue, but I managed to add some depth back into the shot when I overlaid it in Stackables.
Another white flower that was lost in Waterlogue until I mixed it up with Stackables.

So lovely. Thanks for joining the challenge!
It’s all white now!
