In the conservation of wooden panels, it was once common to glue small strips of wood to the back to repair cracks and correct the effects of warping. This reinforcing technique is evident on many wooden panels you buy as antiques. However, in modern conservation this technique, like cradling, has been abandoned because it often leads to further deterioration of the piece. Look out for parquetage de champs (thin strips of wood along the edges) and parquetage à plat (thin strips glued to the back of the panel).
