My paintings oil on canvas

[Božidar Zvekan]

Please advise experienced painters!
I need to paint a painting oil on canvas that is the size of 2.30m to 1m
and should consist of 6 different sizes.
Image is an abstract picture ( I made it on computer in photoshop )

and contains ellipses and circles.
So I can put all the canvas side by side.
When I apart the pieces, I will not get proper extensions lines

from one framed canvas to another.
Anyway, my intention is to print on canvas, on plotter every part of painting,

cut through the canvas, tighten the frame and then I start to paint.

What do you suggest, experienced painters who are already certainly working the big picture?
Thanks for your advice.
