Comparing A to L and other bobbins

Anne Parker

I know some people use Style L bobbins in their machines when they can't find Style A bobbins (mainly in UK where Style A prewounds are difficult to find) beliveing that the only difference is the depth - which is what I thought.

But I came across an interesting document specifing exact sizes for comparison of bobbin Styles.

I though it interesting to see that Style L bobbins whilst shorter than Style A are actually about 2 tenths of a millimeter wider.  I don't know how this would affect the stitch if using them in the 12000/15000 but a sewing machine is a precision machine so I would definitely only use Style A.
