The usual restrictions apply. The design is for personal use. You may use it for gifts. Do not mass produce. Do not make changes or embellishments then call the design your own creations. Nuff said.
The insert I am working on is done in lime green and pink but you can use any colors you desire. After the smocking is complete you can embellish the gingerbread people with back stitches and bows. The same with the Christmas tree. Decorate it up as you would a cookie with icing and sprinkles.
