Here is an inexpensive craft for Mother's Day easy enough for pre-schoolers to do.
Materials:
Lid from laundry detergent bottle
Stickers or pictures of flowers
Bow
Hot glue and glue gun
Potting soil
Small house plant
Decorate your lid with stickers or pictures. Hot glue the bow on (parents can do this step). Fill it up with potting soil and put your plant in. I used a Spider Plant. They always have babies that you can use to start new plants.
We did this in church for Mothers Day this year. The kids enjoyed decorating the planters for their mothers and its a gift that mom can enjoy all year.
