succah 10

succah decorations fade into nothing when they mix with the roofing. they have no significant dimension or cover. they are just beautiful. they are nothing.

(don't need to consider how low the decorations hang when calculating the space under the roofing of a succah. interestingly the examples given in a baraita of succah decorations include fabrics and various fruits and food - items that could become impure and therefore not permitted to be used as roofing)
