Hi I have applied gesso on canvas and have applied three layers. After second layer I realised the corners of the canvas have that effect of cracking which I try to avoid. I sanded the surface and appied a thrird layer thinking that this would correct the cracking corners but it didn't work like that.
Is there any way to avoid this effect when making gesso? and once it crack is there any formule to correct it.
Thanks,
ascen
