To comfortably stretch a canvas over a strainer frame having 2 cm thick 
bars, a canvas margin of about 4 to 5 cm will be needed for sufficient gripping. The canvas is firmly gripped with with a pair of canvas pliers, pulled, held in position, and then stapled in place, as shown in the image here. If the stretcher bar is thicker, add this extra thickness to the above, recommended thickness. The margins of the canvas should have at least this width of all four sides of its sides. This goes for all canvases, whether gallery-wrapped or not. This margin width will allow for the wrapping of the canvas around and over the four sides of the stretcher frame bars. All for canvas margins must be pulled tightly and stapled evenly all ...
types of picture framing. And with that, we also did all methods of mounting. Broadly speaking this mounting process can be categorized as wet-mounting or dry-mounting, and in the latter category, self-adhesive foamboards, feature prominently. It's easy to know why. Properly used, these can offer clean, quick and easy permanent mounting in a matter of seconds. Mounting is more fully detailed and explained in our previous post " 
limitations. Picture frames repairs and re-glazing ( glazing is the covering of a surface with glass ) can be done by most picture framers provided the frame isn't too badly damaged or has just sprung open, as shown in the picture. Other repairs such as retouching of small scratches, replacing broken glass or decayed rear dust covers or broken cord, or string or hangers or nails or screws is also easily enough done. To repair or restore valuable, historical or antique picture frames which need restoration we recommend a qualified, professional art restorer, particularly when antique gilding or hand-carved mouldings ... 
popular one is to 
high breakages claim rates which, however, gradually decreased as our packing knowledge increased with time. In addition, we also learned that the the largest size glass clip frame we can safely ship is (A3 or 29.7 x 42 cm) after which, for the larger sizes, we changed to plastic glass glazing. Nevertheless, and in essence, we pack all glass clip frames with three layers of protective materials which reduces our to damages claim rate to about .01% . In the quite rare occasions that the glazing in the clip frames, photo frames, certificate frames or clip frames does break, we either refund the cost of the broken items or ship ... 
While at first sight that did not seem to be a great issue, we suspected ulterior problems. This is because, in our experience, expert, quality professional taping or hinging rarely fail. When this does happen, it's almost invariably due to the use of incorrect or inappropriate hinging or taping materials, methods, or both. This problem is exemplified by the image below. It shows art taped to a backing with at least four disparate self-adhesive tapes. One is a photograph corner, one a linen tape, one a tan masking tape and the last one, a double-sided tape application. All of them lack any 
of Christian monks known for their rule and habit of silence. And the term "Picture framing" is common enough to be self-explanatory. So why the two terms together? This is because some dodgy, dubious folks tried to trick us into believing that listening to music while we worked was illegal, that we needed to buy their music Licence and that unless we did that, they would prosecute us, get us fined and even jailed. Now then, for those of you who are not in the industry, and thus ... 
incident at our factory outlet some weeks past. To begin with, let's describe the 
framing is concerned. Perhaps the most persistent fallacy is the widespread and popular misconception that glazing ( the covering of framed artwork with a transparent or see-though material ) with 'Plastic Glass', 'Perspex' , 'Plexiglass', a clear plastic, or an acrylic pane is a cheaper more convenient and better alternative than glazing with clear float glass. Alas, and in our lengthy and not inconsiderable experience ...
