1. A hembar comprising:
a first portion that is elongate in a longitudinal direction, the first portion defining a first flange and a first channel;
a second portion that is elongate in the longitudinal direction, the second portion configured to slidably engage the first portion, the second portion defining a second flange and a second channel, wherein the second flange is configured to be received within the first channel and the first flange is configured to be received within the second channel such that alignment is maintained between the first portion and the second portion, and wherein the first portion and the second portion define a slot configured to receive a piece of fabric and an internal cavity that extends in the longitudinal direction; and
a compressible member configured to be enclosed within the internal cavity, the compressible member having a first diameter in a relaxed position and a second diameter in a stretched position, wherein the first diameter is greater than the second diameter, and wherein the compressible member is configured to, when released from the stretched position within the internal cavity, exert a force on the first portion and the second portion such that the second flange is moved further into the first channel in a horizontal direction that is perpendicular to the longitudinal direction and the first flange is moved further into the second channel in the horizontal direction to clamp the piece of fabric within the slot.
