FYI You can find zip bags at Dollar Tree in the laundry section. They come in 3 sizes, the largest (maybe XXL??) is 1 to the box, medium is 2 in box, smaller 3 in box. $1 each box. They are fairly heavy plastic bags. They just aren't the name brand, but do the trick. The dimensions are on the box so check there as I'm not sure of the name of the size shown on box. I can put 3 bed size tops in the largest, the smallest would work for a travel project bag, if I remember correctly.
