Before making a lot of these check for your supply of tissues since the dimensions of various companies tissues appear to vary. Find a set of dimensions that work for you. I found that I prefer to make the length a little more to then overlap the opening by 1/4 " or so to keep the tissues hidden when closed. I purchased the pattern for the "little shirts" and their dimensions were way too big for the tissues I have. After a few attempts I now have a workable set of dimensions.
