They have their level 1 (stretched on a wooden frame and stapled on the back), level 2 (the wooden frame is sturdier), and level 3 (there is some rubber and another wooden frame inside the wooden frame that the canvas is stapled to.)

Gallery wrapped canvas is a method of displaying paintings wherein the edge of the canvas is stretched over the frame and completely covers the stretcher bars beneath: you will not see the staples, the stretcher bars are usually thicker, and the overall presentation is sleek.

A stretched canvas is just canvas that has been stretched on stretcher bars, gallery wrapped is a sub-set of stretched canvases. Gallery wrap basically means that the canvas has been stapled to the back of the stretchers rather than the edges, and I think the rest is speculative. Usually the edges are at least primed.

There are two major fibre types used to make canvas: cotton and linen (flax). Some speciality fibres such as hemp and jute are also used for canvas – we do jute, and although it is a different fibre it is usually considered an extra-rough linen because it is very similar.

I worked at Michael's for a short time and often stocked the canvases. They have their level 1 (stretched on a wooden frame and stapled on the back), level 2 (the wooden frame is sturdier), and level 3 (there is some rubber and another wooden frame inside the wooden frame that the canvas is stapled to.)

Is an artist loft. Level 3 canvas is an archival. Quality heavyweight cotton duck canvas has acid free titanium acrylic white gesso that is primed on the surface.

Gallery wrap: refers to canvases 1 1/2 inch deep or above. Staples or spline in back to hold canvas in place. Mostly exhibited painting or a solid color continuing around the sides of the canvas. However it can be framed IF you can fine a frame deep enough.

Gallery wrap extends and folds your artwork all the way to the sides to completely cover the wood frame. Museum wrap also covers the wood frame but instead of extending your artwork, you choose between white or black wrapping color. Your artwork is limited to the front of the canvas.

Linen canvas is regarded as superior to cotton canvas because the threads are narrower (finer) and the weave tighter. (And Belgian linen the best of all linens). Once stretched and primed, linen canvas is less likely to stretch or shrink, or threads move or distort.

A good canvas will be tight, but will not tear in the corners where it's wrapped. A loosely stretched canvas is the worst!

Canvas is naturally water-resistant, and contemporary forms of industrial canvas commonly feature polyvinyl chloride (PVC) coating on one or both sides for additional waterproofing.

Grade 3 Art focuses on developing more realistic treatments, refining forms and looking carefully at the qualities of objects. Your child will explore different ways to draw and paint and to do printmaking, sculpture, fabric arts, photography and computer graphics. They will begin to experiment with mixing media.
