A retractable quilt clamp apparatus is disclosed having a clamp attached to a strap, and a strap retraction mechanism attached to the strap. The strap retraction mechanism is configured to retract and retain at least part of the strap. The strap retraction mechanism includes a case, a spool, a spiral spring, and a brake. The case at least partially houses and retains the spool. The case and the spool retain the spiral spring. The strap is attached to the spiral spring, which biases the strap to be wound about the spool. The case includes a brake region for retaining and guiding movement of the brake. The brake is configured to press against the strap when in a locked position, and to allow clearance for the strap to move relative to the case when in an unlocked position. A bracket is used to attach the apparatus to a quilting frame, such as a quilting frame of a longarm quilting system.
