1)  1) It is prohibited to have any benefit from wood used to construct the Sukkah, whether it was used for the walls or for the Sechach, until the end of Simchas Torah, and one may not take even a splinter from them to clean one’s teeth. This interdiction applies even if the splinter fell off by itself. It follows that on Shabbos and Yom Tov they are Muktzeh and may not be moved (n.b. one may touch Muktzeh things but not move them). (Kitzur Shulchan Aruch 134)

2)    2) Similarly, one is forbidden to derive any benefit from the Sukkah decorations during the days of the festival. Regarding the decorations, however, one can make a condition. The method of doing this is that one stipulates before the commencement of the festival that one reserves the right to use the decorations during the entire festival, then one may use them, and it follows that they are not Muktzeh on Shabbos and Yom Tov. (ibid)
