Know what I'd like to find? Avery® MPI 4002 Perforated Window Film. But in less than 100-yard batches. A lot less. As in, a few square feet at a time. Seems like the use of this product must generate scraps, way too small for bus windows, but just right for my needs. Any suggestions on where to look for such leavings?
