I love biscornu, I have stitched over 75 of them. Finding a unique button to match the design can be very difficult and frustrating. Here is the solution, a covered button. There are 2 types of covered button available and they come in different sizes. I made a special beaded button for this biscornu, it just enhanced the whole finished piece, do you agree??
The design is by Elizabeth Almond "Lilac Time", the thread I used is Valdani 6 strand overdyed floss "M1002 Water Lilies":
