Step 4: Stencil prep
To center the stencil, mark the middle point of the stencil and the chair with a pencil.
Now apply a light coat of spray adhesive on the back and wait for a minute for it to dry out a bit. This way you can remove it without leaving residue.
So apply the stencil to the chair, using the center marks as a guide. Step away to check to see if it is level. If not, remove and adjust until you're happy with it.
With everything all set, tape or glue other pieces of paper to the side of the stencil.
