The canvas stretching fee typically includes the stretcher bars as they are necessary for the stretching process, but this can vary by provider.
Step-by-step explanation:
When it comes to purchasing canvas stretching services, whether the stretcher bars are included in the canvas stretching fee can vary based on the provider.
Typically, a canvas stretching fee does include the cost of the stretcher bars, as they are essential components of the stretching process. Stretching a canvas is the procedure of pulling the canvas fabric over a wooden frame (the stretcher bars) to prepare it for display or framing.
Nonetheless, it is always essential to check with the service provider for clarification regarding what their fee includes. Some may charge separately for the materials and labor, while others bundle them into one cost.
