here in the USA - we use inches and feet.
your 1.27cm comes out to half and inch. 1/2" or .5".
without a LOT of woodworking experience, you will find
making anything out of 1/2" sticks will be a challenge, to say the least.
plus - your tool inventory is a block.
I would suggest you look around in your area for a carpenter or woodworker
that can assist you with at least putting the frames together.
if you look very closely at the example photo you provided, you can see big wood
behind the material. I would think 1x4 inches on the sides and maybe larger for
the cross sections at the bottom and maybe 1x2 inches in the top half.
there is no way one half inch (1.27cm) will work for this project - sorry.
(photo has been enhanced to show more detail).
so I am referring you back to the Wooden Screen Door as an example.
as an added Edit:
could you please post some photos of the "sticks" that you have ???
here in the U.S., 1/2x1/2" sticks that are 10 feet long will twist up
like spaghetti in a bowl. it is hard to imagine that you have perfectly
straight wooden sticks that are suitable for any kind of projects larger
than a shoe box.
