Stamping tools constructed from corrugated cardboard and a wine cork make beautiful flower motifs. If decorating wrapping paper, stamp a full sheet. To make the cards below, round the edges of colored paper with scissors or a corner punch, apply the markings, and attach to card stock with spray adhesive.
These motifs (including starfish, more correctly known as sea stars) are charming on kids' beachwear, and the process is easy enough for small helpers. Transforming thin cotton fabric into a sarong is a breeze, and the tone-on-tone combination is subtle and sophisticated.
