Maryna, I think it is a matter of personal choice. I am very fortunate to volunteer in a woodshoop and framing shop at our military base, so I get to make all my frames at a discounted rate.(sometimes even free!! Frame, mats and glass!) From my experience, not just
any frame will go with
all pictures. The color of the frame or the style just doesn't go with the color or subject of the paintings, so it may be hard to use one type of frame on different pictures.
I can't seem to help myself!

I have framed everything I have painted, so far!!

(4 paintings-Just can't believe I did them! ) I thought I would use my hallway as a little gallery, using the "same frame" idea you had, but it didn't seem to work. They each have a beautiful frame that matches the color or mood of the picture.
