This is a cute and cuddly dolphin template more than a realistic one! It would be fun to cut two shapes out of grey felt and sew together to make a little dolphin softie, with a little black embroidered or button eye. Alternatively, how about cutting out a number of dolphins from pretty card and stringing them up as a mobile in a baby's room?
Dolphin Template 2
This realistic dolphin template would work brilliantly for a collage scene, with a whole pod of dolphins leaping over the waves. You could even show depth using different sizes of dolphins, with larger at appearing nearer and smaller in the distance.
