Sometime in the past, I picked up some wonderful old thread made buttons. They are wonderfully precise and very tiny. Here are photos:
This is one of the larger ones. Just under an inch in size, it is black and it is worked over a disk shaped button form that has no shank.
These are about 3/8 inch. Imagine crocheting that small on such a little form. It is actually a medium brown in color and seems to be worked over a dome shaped form without a shank.
This one is 3/8 inch, teal colored blue.
Another brown one, 3/8 inch
Another tiny one in dark brown, it really is a different shade than the one above.
This wonderful seems to be a real part of history, quite worn out. The edges are frayed and showing the button form. It is a commercial button and has a metal shank. It appears also that the black "stones" might be some kind of plastic.
A beautiful button, I believe it is unused, no sign of stitching or wear. It is black, crocheted over a domed button form. Measures 1 inch.
Black wrapped with soutache with a rhinestone in the center, almost a sphere. It smacks of being recently made. The ends are glued on the back.
