You could actually do plants. I don't know if you have 99¢ shops where you are but ours has plants and pots. This year my daughter did her OWN teacher gift. We went to Michaels and she picked out a wooden box that her teacher can put pencils in on her desk. She picked her own color and painted it and then glued on those little pre painted wood cutouts(all school related--she chose a chalkboard and actually wrote teachers name in white paint, book which she wrote a title of one of there text books, school house and put the school name on it and then some pencils and other things.) The box was a $ and the cut outs were 5/$ and paint 59¢. I did have to buy the white paint pen but used coupon so it was $2.00. Then she put a brand new box of pencils in it so her teacher would know what it was. I feel for you with so many to buy for. I wish I had some other ideas. I know you can also do the coffee mugs with a bag of coffee or some candy in them. These are cheap to make. You can actually buy plain cups and personalize them. Dollar stores are great for these. I will keep thinking. When do the kids get out of school? We have been out for 2 weeks(son has--daughter went a week longer).
