What type of frame?

[Germa]

mat.

I think it would be easier if you know you want a mat when you start a painting. You could take a canvas, a big as the total picture, when framed, put a mat on to it, draw the mat lines, and paint into that place, in that case, your mat wouldn't wiggle around or go crooked when it is on a stretched canvas.
I can even imagine, a canvasboard works better, when you want to use a matted frame.

If you want to use a mount, Maryna, try one. I would subscribe to Germa's advice, though.
The link you gave shows a double mount. One goes directly on the picture and then another mount, with a larger aperture, is placed on top of the first mount. They can be the same or different coloured mounts.

Maryna,  what you are describing is the way we do it, also. It is very common to use mattes with watercolors. As with all things artistic though, it falls to person taste. I think it's preferable to just frame oils without a matte. As far as the baklijist frame, I don't think you are suppose to use a matte with them.  They do make regular frames with a deeper pocket for paintings on stretched canvas. (I think  I may have just repeated myself on that! sorry! ) I may see if I can talk my friend at the frame shop into letting me do a small little video on framing. The only part of it that might help would be putting the layers together, because we have saws and matte cutters that most of us don't have at home.

C. Bodine that would be wonderful if that would be possible.

Thanks for everyone's insights. I will post a picture of the framed painting once I receive it back.

Thanks

you get what are called inner frames, which are thinner frames which go around the painting, then the main frame goes around that. You get these inners in all sorts of different designs. I will see if I can take a photo or two to illustrate

Then you can also use the paper / board mats that the watercolour artists use around your oil / acrylic paintings. If you do that however, then you need to add glass to protect the mat. It is however true that the oil painting will not be able to breathe, so you have to ensure the painting is not hung is a damp / hot area of the house and definitely not in direct sunlight as the painting will "sweat"

An oil painting framed with a mat can look very expensive, but the problem is that you lose some visibility of the the textures in the painting.

What you are referring to is called a liner, no glass is necessary.  Available in many widths

Nolan mentionned in one of the lesson that he paints on canvas board when he plans to frame, and on stretched canvas when not. 

Is it acceptable to frame acrylic/oil painting on canvas boards in ' Black metal exhibition frames' without any mat? 

What do PB artists use?

Opus (Mary Lynn"s favorite store) has the following, it is back loaded:

Did you do that mixed media painting Annie, it it beautiful. 

[Annie.]

Hi Danielle,
No, my daughter did the mixed media.  I also posted her sunflower.  But I did a poinsettia following the sunflower class and was surprised how much I enjoyed making it.

it is perfectly acceptable to frame a stretched canvas  and this is a perfect frame for the scene, looks lovely
