Always start with a list and check it off as you pack. I have seen so many women get to a retreat without there footpedal or there power cord or feet. These are things at home you just take for granted but when packing you really need a master list. Also after you return from retreat recheck your list to see if you would add anything. Also make sure to label all of your stuff. With that many scissors and rulers in one room you don't want to misplace your stuff.
