For inhouse canvas production we use European knotless pine frames. This frame is extremely hard wearing and does not warp, unlike many of the cheap online alternatives.
Each canvas stretcher frame is milled with a curved profile and rounded edges. This shape helps to minimise contact with the front face of the canvas, preventing unsightly impression marks and surface cracking.
Our canvas frames are all fully finger-jointed. This means that longer frames are made from several lengths of wood pressure-jointed together, helping the frame to resist warping. This combination of techniques helps ensure our canvas frames are exceptionally straight, even at the largest sizes.
