What do You want to Make?
Whether you think you can or you think you can’t, you’re right.
A person who never made a mistake never tried anything new.
What else do I need?
The amount of fabric varies from skirt to skirt based on size. You should have plenty if you bought a yard of fabric for a child and a yard and a half for an adult.
The waist measurement you are using. The elastic should be a bit smaller than waist measurement, so no need to buy extra.
No particular kind is needed!!! Really any machine can make these skirts.
