Our school gets big money too from the basket auctions. Just thought I would give you a couple more ideas... One basket was movie night the kids brought in microwave popcorn,cookies, videos,and all kinds of fun stuff maybe a blanket..
another one was a Tn Volunteer(football) basket and it had tons of things in it football, throw, anything related to UT football............we had a gardening basket, i think they had a wheelbarrel donated and put all the items in it.........and one more i can think of was a barbque basket, they had a gas grill donated,it had aprons and utensils, anythin to do with grilling............
Have fun with it.
Hope
