Darker shades of fabric can change color due to UV radiation.We tested it: We sew bags from the pram and we also have experience with sewing a seat bag and backpack. This material works very well, has a waterproof finish and drops of water flow beautifully over its surface. When cutting and sewing, we did not use pins, which can leave marks on the puncture at the point of pinning, and thus break the waterproof coating, but fixing pins 790355 and 790317, which hold the material perfectly. When sewing, we took care to avoid unnecessary tearing.
