I do believe in the importance of handy skills like sewing , carpentry ..etc. but time hasn't helped .... Actually if sewing is an option I can ask someone to sew a larger pocket to cover the whole flap .. but then again, that would look "new".
Maybe the permenent marker is better, but how "permanent" is it ? I had another bag where an ink pen ran through the fabric of the bag. Also, leaving the bag in the trunk for weeks and weeks in summer heat & humidity will not peel off or discolor the ink ?
BTW, are there any nylon batches that are self adhesive and come in different colors ?
