I want my children to feel involved in the parties that we throw by getting invovled in making the miniature umbrellas for drinks and playdough recipe. I have already arranged for certain items like the decorative paper, toothpicks, craft glue, scissors, pencil, plastic cups etc. Will you please tell me what other accessories do I need? And the most importantly how do I make my children make these miniature umbrellas for drinks? Will it be safe for them, how do I help them and supervise them? My children are 10 and 12yrs old.
