Believe it or not.... I found that free coloring pages on line makes for great hand embroidery designs. You can type in the "Type" of images you are looking for like flowers, Christmas, etc., Coloring books are a great cheap source too.
I trace them out on muslin and go grab my thread boxes to make my color selections. Nice thing is you can pick the pictures that appeal to your level. I'm currently working on a Santa Claus piece for a gift swap. Several people have gotten such pieces from me and LOVE them. And I can match the colors and patterns to their taste.
Sincerely,
Tricia
