How about leather or suede cut in circle or triangle or any other shape and simply put it over the ends and sew it from the top.Triangles and squares are very easy to sew.You can even tack the loops on first for extra security and then attach the decorative leather or suede pieces. Elbow patches are cheap and good for that and they come in many colors too.And they do not frey so you don't have to fold in sides.

Linnea, what a perfect project for the Chinese ball buttons with frogs. For simple directions, google 'Chinese ball buttons and frogs.' One of the best sites is Univ of KY extension services.

I recall, there was once a direction sheet by Mary Hunt, as well. You will be surprised at all the info on this almost lost art.

I have seen amazing frogs that were like flowers, birds and yes, frogs.

Good luck.
