I know this must be one of the most basic things but I have never really built or made anything like this before.... We are going to have a party and I was hoping to purchase something to cover the entire garage door (the big one) so that the guests will use that as an entrance, with maybe a cutout in the middle but I haven't found anything so I was hoping for suggestions. I don't think it will be that cold yet around that time since I live in CA so it wouldn't be a problem leaving the garage open for a few hours. I was thinking I guess black cloth that I have to paint and just attach and drape over the outside but was hoping for something a bit heavier. Any ideas???
