I make ornaments and they sell very well at our church fair. Three or four inch mini traditional quilt blocks in any colors, not necessarily red and green or holiday prints, can be made by making a quilt sandwich with a coordinating backing and thin batting. I layer Warm and White batting on the bottom, then the backing right side up and the block on top, wrong side up. (The block and backing are facing each other.) Sew all around, leaving a space for turning, and then turn right side out and edge stitch all around, catching in the unstitched turning place. Sometimes I've done paper pieced trees in 3 or 4 shades of green. They can be embellished and then finished as above. A hanging loop can be placed between the backing and the block before stitching, or it could be added afterwards. The items on your list sound perfect for a craft show. Have fun, and please let us know how it goes.
