I am Sini Henttu, a Helsinki-based dreamer and an artist. In 2019 I graduated as a Bachelor of Art and Design and continued studying in the Contemporary Design Master’s program at Aalto University. I’ve studied at Aalto since 2015, exploring several materials but mostly focusing on glass and ceramics. In 2018 I studied glassblowing, media art and drawing at Musashino Art University in Tokyo, Japan. Last addition to my studies was exchange in Theatre Academy of Finland, where I participated in performance studies.


At the moment, I’m intrigued by the themes of the human body, humanity, the complexity of the human mind, mental disorders, sexuality and the clash between hopelessness and the overflowing desire to live. In my work there can be often seen subjects as empathy and intimacy. I find themes and ideas from my surroundings, conversations, relationships and my diaries and I often use them as a starting point for my artwork. I’m enthralled by how often themes that are usually thought of as being personal, end up being universal as well.


My work flow as an artist is usually quite intuitive. I start with a hazy vision in my head and let the process take me to unexpected places. In art I’m fascinated by how there are as many interpretations as there are viewers. As an artist my humble ambition is to vomit my absorbing, complexed, but relatable insides for the audience to see, in a way that lets people reflect their lives and emotions.

"I'm always happiest alone"


length: 9:09



"I'm always happiest alone" reflects on loneliness in a society that pressures us into sociality. Everyone feels an individual need for loneliness and each of us is alone in a different way. The desire to be alone is also a privilege that can be safely felt, when social networks and relationships are plentiful and healthy. It’s easy to want to be alone, when you don’t feel lonely.

My video work is often performative, and my work flow is quite intuitive. I usually start with a hazy vision in my head and let the process take me to unexpected places. I’m in love with making videos and I wish to work with it more in the future.

Focus of the piece is on the sleeplessness caused by a disorder – on the gooey twilight zone between being awake and asleep, between real and unreal.


In installations I’m intrigued by how they move in their environment and how people move around them, and how they either blend into or stand out from their surroundings.


l studied illustration as my minor in Aalto. I find drawing soothing, while it's also an interesting way to tell a story. 



Hot work and kiln work made at Musashino Art University.

glass blowing and cold work


The form of the vases tells about the material itself: the glass is so hot it’s constantly moving, pulled down by gravity. Every vase is unique and tilted a bit differently.

green block tower is made with a combination of powder glass and larger glass chunks, which have resulted combination of white and bright glass. The modularity makes it possible to compile the tower in many different ways, so you can mofify it as you like.



Working with ceramics has developed my understanding of form and the three-dimensionality of objects.
