Here is a felt mola I sewed years ago. It is reverse applique- the top layer is teal, light green next, black and pink is the lowest layer. It was just a sample of the technique.
This is another sample (I have a huge box full) of a button and loop treatment. A square of fabric is folded so no raw ends show. Tuck the loop under it and sew around the edges. Sew a square opposite with a button on top.
I made these fabric roses to sit in a thread bowl. Quick and easy: cut a long bias strip, fold in half and gather one long edge. Pull up the gathering threads and roll the flower up. Stitch and add a bottom circle.
