Is it really so strange? Of course it looks very plain, I could have decorated it more but I made it in a haste at night so I just folded the paper up, in fact I like it plain.
I also like to use the reversed envelop to be a book protector, given that I always read book at the pace of a turtle, my book will end in much wear and tear when I finish it.
Actually paper "staff card holder" may not be a good idea, with no lanyard and always wetted by splashing water, so i made a more proper one by adhersive tape and then pretend to be employed by hmv (oh my teenage dream).
