River Mustijoki, Porvoo, Finland

This cloth was dipped into Mustijoki which is a small river in the southern Finland, flowing between the city of Helsinki and town of Porvoo. I took my 7-year-old son with me to do the dipping, he has just started 1st grade. It was a beautiful day, the rapids were almost dry. — Annika
