I will get some photos up in a few days of the inserts I make. I have been sewing my own diapers. Personally, I like flat gauze diapers, but to wear them during the day and wet in them means they have to be a bit thick. By making inserts out of 500 gsm bamboo/cotton fabric about 8" x 30", I can now wear a thin double gauze print diaper with the insert, and it provides good protection during the day without being all that noticeable.
If I drink too much tea and eat watermelon in the evening, as I often do, I can end up wetting quite a bit. Having a well padded diaper with an insert can easily contain the wetness, but I don't always worry about that.
