12 pieces, 4,5 m long and a hand saw later.
Today a friend helped me and we had an adventure! We drowe to a hardware store and the wood I needed were packed in the anount I needed, with plastic bands. So, instead of using a hand saw at the hardware store, we carefully loaded the wood on racks, and secured them, on top of her car and slowly drow to my home. We too ’the scenic’ road so we wouldn’t get angry driver honking their horns at us for driving slowly.
And then we meassured and I used my hand saw to cut the pieces to manageable lengths. Still have pieces to saw apart, but at least the most is done.
