After building the frame, the canvas should be stretched to the right point around it. Below is a proven method of pulling canvases to cover each staple.
Steps
Step 1. Cut the piece of fabric at least 15cm wider than the size of the frame (taking into account its thickness)
This will make it easier to stretch the canvas.
Step 2. Place the frame centrally above the cut canvas
Step 3. Make sure the weave of the fabric is aligned with the edge of the hoop
Step 4. Start on the longest side of the canvas. Fold it around the frame and, using a stapler, insert three staples at the center of the side.
Step 5. Rotate the canvas
Alternatively, stand on the opposite side and pull it firmly, fold it around the frame and insert three more staples at the first.
Step 6. Stand on one of the two remaining sides and pull firmly on the fabric, fold it over the edge and insert two more staples in the center
Step 7. Do the same for the last side of the canvas
Step 8. Reposition on the first side and, starting from the center, pull one piece of fabric at a time and point it to the hoop
Step 9. Repeat the same operation on the opposite side
Step 10. Continue to stretch and secure the fabric to the hoop in the same order as you started
Alternatively you can start closer to the corners and move towards the center.
Step 11. Continue inserting staples up to 10cm from the corners
Step 12. Bend the corners as appropriate and secure them
A good method is to fold the corner back on itself twice so that the edge is flush with the frame.
Step 13. Pull the corners hard, this is the final step and the most important
Step 14. Hammer each paper clip until it is flush with the frame
Step 15. Turn the canvas over and tap the center with your finger
It should sound like a drum. It should be very tense. If the canvas is creased or not stretched enough, remove the staples and rearrange it. It will sag further when painted.
Advice
- By sprinkling with water, moisten the inside of the canvas. As it dries, it will shrink and stretch further.
- Tearing off the excess fabric will be more accurate than cutting it.
- Unprimed canvases are easier to stretch.
- Apply quality primer. Drying will further stretch the canvas.
- Insert small wooden shims in the corners to stretch the canvas further.
- Note: Office staplers are not suitable for this type of work. You will need a stitch shooter.
- Be careful to properly align the fibers of the canvas with the frame, otherwise the sides of the frame may bend and the corners tilt upwards.
- There are special pliers (with a larger surface to avoid tearing the canvas). They are available in art stores.
Warnings
- Put on gloves. Blisters may form when working with your bare hands.
- Be careful with your fingers when using the stapler.
