More-than-human design represents a paradigm shift that decentralises the human in relation to the rest of the living world. As part of this movement, scholars call for a new worldview that recognizes the interconnectedness between human and non-human beings. Prior studies have focused on the experience of human-human connections, leaving the more- than-human largely unexplored. Addressing this gap, this study explores design strategies for fostering feelings and reflections of interconnectedness towards the more-than-human world and associated emotions. With a research-through-design methodology, two workshops were conducted, resulting in six key design strategies and an "interconnectedness experience framework". The strategies were evaluated through a prototype in partnership with AquaPrint, a Swedish company that up-cycles fishing nets into designer furniture. Future research should evaluate the strategies individually and in combinations as well as in a field setting. The presented framework and strategies are intended for practitioners as inspiration in design projects to promote noticing the more-than-human world, and encouraging a posthuman perspective.
