My fiancee and I decided that we want to give our parents custom photobooks of each of us - some with moments of us from our childhood, but primarily (if not entirely) from the wedding. However, we want to give them something to open up still. Any suggestions on how to present this IOU/belated gift present in a classy/unique way that let's them know we did not forget about them? Any and all ideas appreciated! Thank you in advance!
