SOURCE: making a buttonhole on a Necchi 3204 sewing machine

Here's what the manual says:

Before sewing, fit the button-hold foot to the machine (long white plastic thing with red, ruler like markings).

Select the pattern selector dial that is solid green on the left hand side. Set the dial to "1" position. Sew the left side and raise the needle.

Select the pattern selector dial that is solid green on the top and bottom. Set the dial to "2" position. Sew 5-6 stitches and raise the needle.

Select the pattern selector dial that is solid green on the right hand side. Set the dial to "3" position. Sew the right side. Raise the needle.

Select the pattern selector dial that is solid green on the top and bottom. Set the dial to "4" position. Sew 5-6 stitches and raise the needle.

Hope that helps...

You can also use a Eureka vacuum cleaner belt, can't remember the exact model, but the package says it's for most sewing machines. It's not the V belt, but it works on my Super Nova and it's 1.79 for two!
