If the furniture of a Swedish Möblelhauses would build so quickly and easily, there would be only satisfied customers. It would be nice yet a ventilation window, longer tapes to fix the rolled-door, long pegs, to the cords to tie down in green. We have resorted to us: with a utility knife gently A4 sized piece cut into the back wall (of course, sides and bottom -above not) that you can roll up and secure with a clothespin. Green extension ribbon knotted. Bought Green cord and long pegs. Can one make-but everything must not be. Two thumbs up !!
