The Ring is up in Nimman, near the university. The sewing studio is on the second floor, tucked away down a hallway. I loved it! They're quilting-focused, so I just bought some good scissors and a marking pen. The owner is such a doll- she checked whether the pen worked by using it on her shirt! There's a sewing circle there, but I've never been.
They only have a Facebook page: https://www.facebook.com/SewingStudioAtTheRing?fref=nf
