Meet Kasia Polkowska & Kyle Cunniff

Where Is the Kasia Mosaics Studio Located?

The private Kasia Mosaics Studio is located in Alamosa in the San Luis Valley in Southern Colorado. It is a working studio that is not open to the public and does not have regular business hours. As much as we'd love to invite everyone to visit, we cannot accommodate casual visitors with our busy schedule. If you are interested in buying artwork, an appointment can be scheduled.

Kyle and Kasia in Alabama, US with the Kasia Mosaics Flower Class.

Kasia Polkowska is a stained glass mosaic artist and an entrepreneur.  Kyle Cunniff is her collaborative partner in art and in life.  He is an artist, a designer and an assistant mosaic instructor.  The duo met at and graduated from New York City’s Pratt Institute in 2006 where Kasia earned a BFA in Painting and Kyle earned a BID in Industrial Design.  Since completing their studies, the couple has been traveling the country while pushing each other in various artistic endeavors, most recently delving into outdoor sculpture and murals.

At the beginning of 2014, Kasia and Kyle began teaching Kasia’s approach to the stained glass mosaic process via in person classes in Colorado.  Since then, they have taught hundreds of students, having each of them complete their very own mosaic in the allotted class time. In 2015, they took an 8 month road trip across the US, teaching pop-up mosaic classes in many places that they would otherwise never imagined being able to offer a class.  It was quite a ride to say the least! More recently the duo decided to focus on Online Education, now having two fully virtual workshops available to students worldwide – the Online Flower Class and the newly released Online Owl Class.

Kasia and Kyle have created this website together to share online courses, project kits and more! The page was designed to encourage people of all backgrounds and skill-levels to give stained glass mosaics a go!

The class is so instructive and easy to understand. Close up videos are so helpful and informative...a wealth of information! ~ Patty from Texas

Teaching Experience

Kasia has taught in person as well as online classes to 500+ students since 2014.

Rich, Engaging and Extensive Class Content

Each of Kasia’s Online Classes has hours of video content divided into easy to follow lessons that each come with supplementary written text and imagery. Each class includes a full set of project templates at no additional cost to the students.

Impressive Art Portfolio

More and more people are trying to teach mosaic classes in person as well as online. One way to judge your teacher is by their own portfolio.

What are the students creating?

Another way to judge your teacher is by the work their students are able to create as a result of taking their class.

Online Courses

And Counting...

Don't wait. Start something creative today.

I have a lot of students say to me when they do finally take a class “I don’t know why I waited so long to try this out!”

With my classes you get all the support you need to start your mosaic even for a complete beginner. Don’t wait. Try out something fun and creative today.

Any artform or creative endeavor takes practice. As the old saying goes if you don’t succeed the first time try, try again. What we learn from working with glass is that when we do it wrong, it breaks. When we do it right, it breaks right 🙂 Practice. Practice. Practice.


This is one medium you really can’t fast forward through. Its a meditation. Respect the glass and it will respect you. Try your best to relax and get into the rhythm of work. If its not working out today, take a breather, stretch, go for a walk and come back refreshed, works every time.


Stick with it. You work hard and you get rewarded. Get excited about the next piece and the next. Working with stained glass mosaics is the constant reward and reminder that each new piece cut, trimmed and shaped makes you better at what you do and your work will show for it.
