Hi,

Do ya'll think 32oz of edible sequins will completely cover a round 10" X 5" tall cake?

If not, how much oz or lbs would I need? Thanks

That will be a quart, give or take a little bit on the volume.  I would think that would be plenty.

it’s probably enough but it’s 32 ounces in weight not volume — the quart is volume — 

in this case the size of the bag, the dimensions of, is more important than the actual weight —
