Over the years, I have seen many copies of vintage samplers that little girls learned their alphabet from making them. However, depending on the year, you will note that the letter appears to be missing. Then no longer. It is simple really. There was no such thing as the letter J for a very long time and the I was used in place of it.
So if you really want a sampler that you are embroidering to look authentically old, leave that J out and just use the I.
