It's hard sometimes to shop on line but I did need a particular look of button to go with a specific project. These buttons are SO pretty in person. Mother of pearl - which was exactly what I wanted! Well made buttons with the shank on the back - and the shank is NOT large at all - which also is great if you intend to put these on a sweater. I was concerned the button shank would be too large causing the button to dangle more than sit well on the finished garment so these will show off more like jewelry accents than cheap plastic buttons from a fabric store. Perfect buttons, perfect size, wonderful quality, and they were available in the quantity I needed(which isn't often the case at my not so local yarn shop) Once again I found just what I needed at Jimmy Beans Wool.
