A molding strip for fabric and wall systems has a base for securing it to a wall and at least two pairs of flexible gripping members that face each other at fabric entry slots for different fabric receiving cavities. In one embodiment, one pair of flexible gripping walls is arranged where an edge of the base and an adjacent wall or ceiling intersect and the other pair is arranged on a protruding member. The flexible gripping walls have gripping teeth to secure the fabric after insertion of fabric into a collection cavity.
