Hello,
Yes, the price that is listed is just for the pattern. Any supplies you need have to be purchased separately from the pattern.
The best way to know what a product is, is to look at the Product Type that is listed right above the price :) Product Type: Plastic Canvas leaflet means it's just the pattern. Pattern Type: Plastic Canvas Kit means it's a whole kit and everything you need will be inside.
Hope this helps!
