We enroll everyone on a first come/first serve basis. We must have this information to secure your seat.
You will receive a confirmation within a few days confirming your registration. If you have any questions please email us or call us at 773-865-6777.
Please Note: The age minimum for Groupon participants is 8 years oldwhen accompanied by a parent/guardian.


Due to the high demand and limited spaces, cancellations must be made more than 2 business days before your workshop in order to reschedule your spot. If you reschedule within 2 business days or less before your booked date, -OR- after your booked date (no-show and reschedule after), you will be charged a $20/person rescheduling fee.
Late Arrivals: If you are 30mins or more to your Groupon workshop, you will be charged a $20/person rescheduling fee due to workshop sizes.
You may also opt to use the amount of your unredeemed Groupon purchase towards any CMS class or workshop.


Please note that the expiration date of your Groupon is based on the date of purchase (4 months from the date of purchase). CMS is in compliance with Groupon policy, and as such the expiration date acts a deadline to enroll. As long as you redeem your voucher by enrolling within the valid period, you can select from any upcoming open workshop date.
If your Groupon voucher has expired, the paid value will remain valid and you may use the value of the purchase towards the full cost of any class or workshop at CMS. The retail value of the Mosaic Basics Workshop is $90/person. 
We can’t wait to see you at CMS!
