T-shirt design: three sisters

A t-shirt design for three siblings. The design of the older siblings (Sol and Luna) was created in anticipation of the third child. They reach for a star (symbolically their sibling), which as the youngest (Stella) is related to both of them (sun and moon).
The motifs are applied to the T-shirts using flock (a fluffy material), which should be a haptic experience for the children.
