Kevin is correct--one cannot afford to purchas a "ready-made" of a 72 inch x 87 inch canvas... I build my own stretchers and stretch and prime my own canvases...there is no other way. Further, as stressed, storage is always a problem. I have tried to free up my storage facility--too expensive--and have rolled numerous paintings like large carpets. The problem with rolling up large canvases is that they almost never see the light of day again--since nobody wants to buy them--and exhibiting is difficult, due to exhibition space limitations; they can suffer damage (cracking, flacking, etc.), as well. Restoration is generally simply, should someone call for the need. In summary, painting on large scale is artistically rewarding, and unleashed my abilities at an early age (mostly during the 1980's), but is also impractical, and has become burdensome as I age. Now, living in smaller confines (I once owned a house with large work area), I no longer can physically fit large paintings, like 72 x 87. The tide has changed; I have become "smaller-minded."
