Scroll Rods 14"

Rec'd scroll rods and they were as I saw in the ad. The ad picture was a bit difficult to see detail and I would have liked some info about the size of the screw part to make sure it would match the size of my exsiting frame piece (knobs). However, the fabric (to baste the cotton Aida onto) did not come with the rods - even though on the packaging of the rods it says "Important - two part system! Part 1: rods, Part 2: fabric". Nowhere on the ad did it state that fabric was to be purchased separately. Waiting for a response from the company if fabric is backordered or if separate purchase is required.
