And once you do find a pattern you like, you may surprise yourself at how easy they are to 'cut a little different' here, 'add a little something' there, and you are creating your own purse/bag patterns. Most are easy to enlarge or reduce also.
I would like to add: When making anything from a pattern, it is best to read the patterns over before cutting any fabric. Read and re-read to make sure you understand the patterns to get the end result you are looking for. I have done several purse and bag patterns, and there was one that I found with errors and I even knew a much simpler way to make part of the pattern, which saved me a lot of time. This pattern I bought had the order of creating the bag a little mixed up and it was confusing. I did contact the designer of the bag with my thoughts. Possible some of you know which one I am talking about. (It is not a Bow Tuck) The bag did turn out great though and my DIL loves it.
