I was thinking of just doing a bunch of alphabet and number cookies. Need easy and not a lot of time. Any other ideas? Thanks!

It doesn't have the 'techer's' theme if you were going for that but they do have the ' afternoon tea' theme but you could just do like simple tea cups or simple coffee mugs (have some in my gallery) or maybe you could do some books or something like that...sorry that's all i got lol

I did apples a couple years ago. They went over well. Not too much detail and only used 3 colors.

what about mini chalkboards? green background and could do teachers' names, or ABC or school name on the chalkboard?
Or something with the school mascot?
That's very nice of you to do! As a former teacher - we were so appreciative when someone did something like that. They will love whatever you do!
