Let the kids do them, make them from their pic. they color or use colored construction paper, with a small piece of lightweight cardboard then laminate them. You could still include the poem about what they are for, and add a tea bag in the gift pkg. I'm a retired 1st grade teacher and I always had my students make their own Mother's Day gifts and Christmas gifts. They may be strange looking or perhaps a little crude to some, but I always loved whatever my own two children made and gave me, whether from school or Sunday School at Church. They meant so much because my children did them, and I still have many of their gifts and cards, youngest is 37 and oldest is 40 now. Children like to do their own things and are always so proud of what they do. Each one would always think theirs looked the best in the class. Just a suggestion. You could supervise, but let the children do the work. They may be too young to get into the sewing, but they could weave placemats, or the mug rugs with construction paper. When they are laminated, they will hold up for a short time, but the kids will feel like it is truly a gift from them, and not something the teacher did for the mother. Just my opinion.
