I ordered this 3mx3m alternative roof sheet. So far nothing to say except that in the description it was not clear how the upper part of the roof was fixed. So, the arbor is left without this piece of roof over since it is an arbor capless provided to secure this part of canvas. We'll have to patch up and I do not know how. For attachments, must be extended because any "scratches" are actually too short or too distant. Too bad that in the description there is no more information to facilitate the purchase (or not) - explanation for saying what kind of arbor this painting is intended.
