Highlighting and contouring in Photoshop: Fill a blank layer with grey and place it on the soft light blend mode. Then paint with either a low opacity white paintbrush to highlight or a low opacity black paintbrush to darken.
Green craft project idea - Repurpose a tuna can and clothes pins to make a flower pot or candle holders. Would be cute to do with a kid to work on fine motor skills. Would be cute for grandparents or as a Mothers Day gift! =) mothers day present :)
